The plaintiff below, Gary Reeves, seeks to disseminate certain political and educational views among the people of Houston, Texas, through the use of sound amplification equipment. Houston regulates such activity in section 29-6(a) and (b) of the city’s Code of Ordinances, which requires in subsection (a) that one obtain a permit and in subsection (b) that one comply with specific restrictions on the use of sound amplification equipment outside of buildings or residential property. 1 Reeves filed this action challenging the restrictions contained in subsection (b) on the grounds that they are an unconstitutional infringement of *381 free speech protected by the First Amendment. The U.S. District Court for the Southern District of Texas found the restrictions to be unconstitutional because of overbreadth and vagueness and enjoined the city from enforcing them. The City of Houston appealed. We affirm in part and reverse in part.
I. The Standing Issue
The City of Houston first attacks the jurisdiction of the district court on the grounds that no “case or controversy” under Article III exists because subsection (b) has never been enforced against Reeves or anyone else. In the first place, the record indicates otherwise. On June 1, 1978, the office of the city tax assessor and collector denied Reeves a permit to operate a sound truck in the downtown district' during the week of June 1-7, and the only authority for that refusal was subsection (b). In the • second place, the Supreme Court has often rejected the rule of standing that would require a plaintiff to submit to arrest or point to the arrest of another before he may challenge the subject ordinance in federal court.
See, e. g., Babbit v. United Farm Workers,
The record below contains abundant evidence that Reeves’ fear of prosecution or direct injury is not in the least hypothetical. He engaged in conduct prohibited by subsection (b) both before and after the district court enjoined the enforcement of the ordinance. At trial Reeves alleged a desire to use sound equipment in ways that would violate each of the provisions of subsection (b).

Conversely, the city gave strong indications that subsection (b) is “not moribund,”
Doe v. Bolton,
*382 II. The Constitutionality of Section 29-6(b)
A. Supreme Court Precedents and Standards
1. Municipal Regulation of Sound Amplification
The power of municipal governments to regulate the use of sound amplification equipment first came before the Supreme Court in
Saia v. People of State of New York,
At the same time, the Court recognized in
Saia
that when the exercise of First Amendment rights infringes on legitimate state interests, a city may enact narrowly drawn statutes regulating the time, place, and manner of such activities.
Less than one year later the Court upheld a Trenton, New Jersey, ordinance which prohibited the operation on city streets of any sound amplification equipment making “loud and raucous noises.”
Kovacs v. Cooper,
The judicial task in balancing such regulations against the exercise of First Amend
*383
ment rights was more fully discussed in
Grayned
v.
City of Rockford,
2. Overbreadth
If, at the expense of First Amendment freedoms, a statute reaches more broadly than is reasonably necessary to protect legitimate state interests, a court may forbid its enforcement. But the Supreme Court has cautioned that invalidation of state laws for facial overbreadth is a remedy that should be applied “sparingly and only as a last resort.”
Broadrick,
3. Vagueness
Several provisions of subsection (b) were also challenged and invalidated for vagueness under the due process clause of the Fourteenth Amendment. The traditional standard of unconstitutional vagueness is whether the terms of a statute are so indefinite that “men of common intelligence must necessarily guess at its meaning and differ as to its application.”
Connally v. General Construction Co.,
B. Restrictions as to Time and Place Subparagraphs 1, 2, and 5 of the ordinance restrict the time and place of the use of sound amplification equipment. Subpar-agraph 1 prohibits all sound amplification in the downtown business district except for certain hours on Sunday. Subparagraph 2 prohibits all sound amplification throughout the city between 7:00 p. m. and 10:00 a. m. daily and between 10:00 a. m. and 1:00 p. m. on Sunday. Subparagraph 5 prohibits all sound amplification within 100 yards of a hospital, school, church, or courthouse, or within 50 yards of any residence including a hotel or motel. In order to appreciate the degree of restriction these subsections cumulatively impose, it is useful to note that they leave only the following outside areas and times open to the use of any form of sound amplification equipment, no matter how low its volume or orderly its presentation:
1) the downtown business district between 1:00 and 7:00 p. m. on Sunday afternoons;
2) parks, industrial areas, and purely commercial areas 6 between 10:00 a. m. *384 and 7:00 p. m. Monday through Saturday and 1:00 and 7:00 p. m. Sunday;
3) those residential areas where houses are set back from the road at least 50 yards, and then only between the same hours specified in 2), above.
Even these listed areas would be foreclosed if the amplifying equipment were within 50 yards of a residence of hotel, or within 100 yards of a hospital, church,.school, or courthouse.
The city asserts two justifications for the restrictions contained in subpara-graph 1 in regard to the downtown business district: 1) to prevent disruption of the normal business activity on the crowded streets in this district and 2) to prevent distractions of pedestrians and drivers whose full attention is needed elsewhere. The ends which the city seeks to protect are clearly proper, but the blanket prohibition by which it seeks to achieve those ends is far too broad. Not every amplified sound at every time except Sunday afternoon will disrupt the normal business activity of the downtown district or make the streets unsafe. Precisely because the downtown district is already a busy and noisy place, reasonably amplified free speech is guaranteed a broad right to equal participation in these aspects of modern urban life. As the Court stated in
Grayned,
“the nature of a place, ‘the pattern of its normal activities, dictate the kinds of regulations of time,, place, and manner that are reasonable.’ . . . The crucial question is whether the manner of expression is basically incompatible with the normal activity of a particular place at a particular time.”
Grayned,
The city attempts to justify the subparagraph 2 restriction on hours of operation as a reasonable means of preserving the tranquility of Sunday morning for religious services and of the evening, night, and early morning hours for rest, quiet reflection, and family togetherness. It is true that when a citizen is within the privacy of his home, the state has broad powers to safeguard his “very basic right to be free from sights, sounds, and tangible matter” he does not want.
Rowan v. United States Post Office,
Subparagraph 5 seeks to protect specific locations where the city has a legitimate interest in preserving privacy and efficient operation: residences,
7
schools,
8
courthouses,
9
hospitals, and churches. But here, in contrast to subparagraph 2, the city protects the location without regard to the time or normal activity of the area. For instance, there can be no valid state interest in prohibiting all sound amplification within 100 yards of schools, courthouses, and churches outside the normal hours of use, as does the City of Houston. And if a residence or hotel is located in an area characterized by noise and activity at a certain hour, amplified free speech may participate in that noise and cannot be absolutely prohibited within a fifty yard protective zone. There is no valid state interest in prohibiting amplified sound that does not actually cause, or imminently threaten to cause, material disruption at these locations.
10
See, e. g., Grayned,
C. Restrictions as to Manner
Subparagraphs 4, 6, and 7 regulate the manner of use of sound amplification equipment. The first of these provisions requires sound trucks to move at a speed of at least 10 m. p. h. unless impeded or stopped by the flow of traffic and to cease broadcasting one minute after being stopped. The city argues that the operation of a sound truck in any other manner would constitute a traffic hazard and create danger for both motorists and pedestrians. At the same time, the city offers no evidence to support this broad claim. Such a generalization is undoubtedly true in certain times, places and situations-but not always. The city may define a traffic hazard or an unsafe speed of operation for any vehicle and apply the same standard to a sound truck. But if other vehicles are allowed to move slowly or stop on a certain street, a sound truck may also do so until it has actually created, or imminently threatens to create, the same kind of material disruption or danger to traffic and pedestrians that would be objectionable if caused by any other vehicle or activity. This subpara-graph is not narrowly tailored to protect the city’s legitimate interests, and is accordingly void for unconstitutional overbreadth.
Subparagraph 6 requires the volume of sound amplification to be controlled
*386
so that it is not “unreasonably loud, raucous, jarring, disturbing, or a nuisance to persons within the area of audibility.” The district court found that the terms “unreasonably” and “nuisance” are imprecise, do not give the ordinary person fair notice of prohibited conduct, and allow arbitrary and discriminatory enforcement by officials. The court therefore found this subpara-graph to be void for vagueness under the Fourteenth Amendment. We disagree. The Supreme Court has approved the use of the word “unreasonably” in similar statutes that are otherwise precise and narrowly drawn.
Cameron v. Johnson,
The remainder of the prohibitory language in subparagraph 6, “disturbing ... to persons within the area of audibility”, presents a closer question. The Supreme Court has expressed reservations about the word “disturbs” in a similar ordinance. But in the expectation that a state court would interpret the term objectively to mean “actual or imminent interference with . . . ‘peace or good order’ ”, the Court eventually found the term not unconstitutionally vague or overbroad.
Grayned,
Subparagraph 7 prohibits the operation of any sound amplification equipment “with an excess of twenty (20) watts of power in the last stage of amplification.” At trial the plaintiff made much of the fact that a regulation based upon decibels at the point of hearing, rather than watts at the point of amplification, would more precisely relate to the city’s interest in keeping sound within non-disruptive levels. That is undoubtedly true, and the district court used the existence of this “least restrictive means” as the basis of finding subpara-graph 7 unconstitutionally overbroad. But the requirement that a statute be “narrowly tailored” is only one factor in answering the ultimate question whether the regulation is “reasonable.”
Grayned,
But the number of watts chosen as the point of regulation must also be reasonable. The district court made no finding as to this issue because it invalidated subpara-graph 7 solely on the grounds that it is wattage-based. Our examination of the record shows that the plaintiff’s expert witness testified that sound amplification in excess of 20 watts could be non-disruptive. The city did not offer any contrary evidence, and thus conclusively failed to meet its burden of justifying the regulation.
Tinker,
D. Restrictions as to Content
Subparagraph 3, prohibiting the amplification of words or sounds that are “obscene or slanderous,” is the only provision of section 29-6(b) which operates as a prior restraint on the
content
of the sounds and speech amplified, rather than merely the time, place, and manner. As such, it is subject to an even more exacting judicial scrutiny.
Police Dept. of City of Chicago v. Mosley,
The plaintiff also raised a vagueness challenge to the “obscene” provision of subpara-graph 3. The Supreme Court has previously decided that this term is precise enough to convey “sufficiently definite warning . .. when measured by common understanding and practices.”
Roth v. United States,
The district court invalidated the subparagraph 3 prohibition of “slanderous” speech on grounds of unconstitutional vagueness. The district court reasoned that the common law of slander and libel has been greatly modified by the Supreme Court in a series of landmark cases beginning with
New York Times Co. v. Sullivan,
III. Conclusion
Throughout this opinion we have affirmed the ability of the City of Houston to legislate- in this area. We are certain that most citizens desire protection from unreasonable or disruptive levels of noise on the streets and from uninvited noise within the privacy of their homes. We say nothing today that prevents the city from granting that protection. When the city fears disruption, it may prohibit conduct that actually causes, or imminently threatens to cause, material and substantial disruption of the community or invasion of the rights of others.
Tinker,
Accordingly, we agree with the district - court that subparagraphs 1, 2, 4, 5 and 7 are void because they unnecessarily infringe upon rights protected by the First Amendment. We also agree with the district court that the term “slanderous” in subparagraph 3 is void for vagueness under the due process clause of the Fourteenth Amendment, and we additionally find it overbroad in violation of the First Amendment. We reverse the district court holding that subpar-agraph 6 and the term “obscene” in subpar-agraph 3 are unconstitutionally vague.
AFFIRMED IN PART, REVERSED IN PART.
Notes
. As originally enacted by the Houston City Council in early 1976, section 29-6 read as follows:
(a) No person shall use, or cause to be used any sound amplifying equipment outside of buildings or other enclosed structure within the city without first obtaining a permit to do so except on residential property. Such permit:
(1) May be obtained by making application to the tax assessor and collector.
(2) Requires payment of a five dollar ($5.00) fee.
(3) Will be valid for a one-week period and may be renewed without charge for an additional one-week period any time during the succeeding ninety (90) days.
(b) The use of sound amplification equipment outside of buildings, or other enclosed structures within the city, except on residential property, is subject to the following regulations:
(1) The operation of sound amplifying equipment is prohibited Monday through Saturday within the downtown business district. A permit must be obtained for the operation of such equipment in these areas on Sundays. Any such Sunday permit shall state the business district to which same applies and shall be valid for only one day. Each separate Sunday must have a separate permit. Provided, however, that the provisions of this section shall not apply to parade permits which have been obtained from city council.
(2) The operation of sound amplifying equipment is prohibited between the hours of 7:00 p. m. and 10:00 a. m. daily, and further prohibited on Sunday between 10:00 a. m. and 1:00 p. m.
(3) The sounds amplified shall not be obscene or slanderous.
(4) The sound amplifying equipment on a sound truck shall not be operated unless the truck is moving at a speed of at least ten (10) miles per hour, except when the sound truck is stopped or impeded by traffic. When the sound truck is stopped by traffic, the sound amplifying equipment shall not be operated for longer than one minute at each such stop.
(5) The operation of sound amplifying equipment is prohibited within one hundred (100) yards of any hospital, school, Church or courthouse.
(6) The volume of sound amplified shall be controlled so that it is not unreasonably loud, raucous, jarring, disturbing or a nuisance to persons within the area of audibility.
(7) No sound amplifying equipment shall be operated with an excess of twenty (20) watts of power in the last stage of amplification.
On May 16, 1978, the City Council amended and re-enacted section 29-6. The only significant amendment, however, was the following addition to subparagraph 5:
(5) The operation of sound amplifying equipment is prohibited . .. within fifty (50) yards of any public or private residential structure. For the purposes of this ordinance, ‘public or private residential structure’ shall mean any structure wherein a person or persons reside, either temporarily or permanently, including but not limited to single family and multifamily residences, apartments, duplexes, condominiums, motels, hotels, boarding houses, and rooming houses.
.As the first paragraph of part II.B. below demonstrates, the reach of subsection (b) is so broad that we have no difficulty imagining that Reeves would violate each subparagraph of subsection (b) in any dedicated use of sound equipment, with the exception of subpara-graphs 3 and 6. His standing to challenge the entire ordinance is unaffected by such reservations, however, since standing requirements are less demanding when First Amendment freedoms are endangered. In that context, the Supreme Court has traditionally relaxed the normal standing requirements “to take into account possible applications of the statute in other factual contexts besides that at bar”,
N.A.A.C.P. v. Button,
. On May 14, 1978, Reeves was arrested for operating sound amplification equipment inside the city without a permit in violation of section 29 6(a). He is still charged in Houston Municipal Court with the violation of subsection (a), but that pending state charge is not in dispute in this case and is significant only as an indication that subsection (b) itself has vitality. The Houston City Council re- enacted and strengthened subsection (b) on May 16, 1978. Reeves filed suit on May 26, 1978.
. The city argues that if Reeves’ standing to challenge subsection (b) were based upon his arrest under subsection (a), the district court should have dismissed under
Younger v. Harris,
We do not base our affirmance of Reeves’ standing on a unitary view of subsections (a) and (b): it is clear that Reeves’ prosecution
*382
under subsection (a) will not require the state court to consider any provision of subsection (b). There is thus no pending state action related to this case, and hence no basis for
Younger
abstention.

. Three Justices joined a plurality opinion interpreting the ordinance to ban
only
“loud and raucous” sound amplification and saying in dicta that a total prohibition would “probably” be unconstitutional.
