BASHARA, J.

Plaintiff, United Pentecostal Church, is a religious organization located in a residential neighborhood of the City of Muskegon, Michigan. Early in the summer of 1971, the city issued criminal complaints and warrants against plaintiffs as a result of allegations by several of the residents surrounding the church property. The residents were apparently disturbed by loud music and prayers emanating from the church during its evening services, especially as those noises appeared to come from sound amplification equipment.

Plaintiffs were charged with violation of § 8-306 of the Code of Ordinances of the City of Muskegon which provides as follows:

"It shall be unlawful for any person to make, continue or cause to be made or continued any loud, unnecessary or unusual noise or any noise which either annoys, disturbs, injures or endangers the comfort, repose, health, peace or safety of others, within the limits of the City."

Plaintiffs thereafter sought an ex parte injunction and writ of superintending control from the Muskegon County Circuit Court asking that the district court be restrained from hearing the criminal cases against plaintiffs. The grounds for these requested orders were that the ordinance was unconstitutionally vague and overbroad by use of the words "unnecessary or unusual", "loud", and "annoys" to describe prohibited noises. The circuit court denied plaintiffs' requested relief and granted summary judgment in favor of defendant City of Muskegon. Plaintiffs appeal, challenging the constitutionality of § 8-306.

A municipality of this state has a legitimate objective in the protection of its citizens from those noises which may affect their health, morals, and safety. It has also been stated that "the police power of a municipality comprehends the duty, within constitutional limitation, to protect the well-being and tranquillity of a community". 56 Am Jur 2d, Municipal Corporations, Etc, § 470, p 519. The question this Court must decide is whether the City of Muskegon has exceeded those limitations requiring specificity of terms in the enactment of ordinance 8-306.

We referred to certain general rules regarding specificity of penal ordinances in the case of Dearborn Heights v Bellock, 17 Mich. App. 163, 166; 169 N.W.2d 347, 349 (1969), stating:

"A penal ordinance must have an ascertainable standard of guilt. Herndon v Lowry (1937), 301 U.S. 242 ( 57 S Ct 732, 81 L Ed 1066); Winters v New York (1948), 333 U.S. 507 ( 68 S Ct 665, 92 L Ed 840). The terms of such an ordinance must be sufficiently explicit to inform those who are subject to it as to what conduct on their part will render them liable to its penalties and to guide judges and juries in the fair administration of the ordinance without resort to speculation and conjecture. Herndon v Lowry, supra; Musser v Utah (1948), 333 U.S. 95 ( 68 S Ct 397, 92 L Ed 562); Boyce Motor Lines, Inc v United States (1952), 342 U.S. 337 ( 72 S Ct 329, 96 L Ed 367)."

The Court in Bellock, supra, was concerned with a loud party which the Court did not consider to be a constitutionally protected activity. Where the activity to be regulated is safeguarded by the First Amendment, as in this case, the standard of permissible statutory vagueness becomes more strict. Keyishian v Board of Regents, 385 U.S. 589, 604; 87 S Ct 675, 684; 17 L Ed 2d 629, 641 (1967). Applying the standard of Bellock and Keyishian, supra, to the controverted ordinance, we conclude that the language fails to establish sufficient ascertainable standards of conduct. The terms "unnecessary" and "annoy" require men of common intelligence to guess at its meaning. The infirmity in the use of the word "unnecessary" to describe that noise to be prohibited was well stated in Phillips v Borough of Folcroft, 305 F. Supp. 766 (ED Pa, 1969), at p 770-771:

"At the outset we observe that the defining adjectives contained in Folcroft Ordinance No. 136 are used in the disjunctive. Thus, a person can be convicted of disorderly conduct for making only `loud noises'. * * * It could be argued that ordinance 136's use of the adjective `loud' to define disorderly conduct, without any further modification of `noise', is itself sufficiently imprecise not to withstand constitutional scrutiny. The death knell is sounded, however, by the use of `unnecessary', in the disjunctive, to modify `noise.'

"We do not think it requires much discussion to establish the vice, in the area of First Amendment freedoms, of defining disorderly conduct to mean `the making of unnecessary noises'. The definition of proscribed conduct in this manner permits

"`so much free play that in the practical course of [the ordinance's] operation it is likely to function erratically — responsive to whim or discrimination unrelated to any specific determination of need by the responsible policy-making organs of society — and to result in a significant number of impermissible public-versus-private-interest resolutions which are beyond the effective discovery or appraisal of the Court.'

* * *

"However, as we have indicated, the real vice of this language is that it permits police and other officials to wield apparently unlimited discretionary powers in choosing those persons in violation of the ordinance. * * * This is clearly an impermissible judgment under the First Amendment."

In finding that Muskegon's "anti-noise" ordinance 8-306 is unconstitutionally vague, this Court does not condone interference with the peace and sanctity of one's home by loud noise. This admonition applies to constitutionally protected activities as well as those unprotected. We are persuaded that a more clearly and narrowly drawn ordinance can achieve the municipality's objectives while insuring an ascertainable standard of guilt for due process requirements.

Reversed. No costs, a public question being involved.
