Movie theater sound regulations are a contentious issue, with some people arguing for standardized volume limits to protect hearing, while others argue that this would violate the First Amendment right to free speech. While there is an industry standard, there are currently no regulations on sound levels in theaters. This has led to concerns about hearing damage, especially with the transition to digital sound, which can be increased to extreme levels without distortion. The Motion Picture Association of America (MPAA) and the National Association of Theater Owners have agreed that movie trailers should average no more than 85 decibels, but this is not consistently enforced. Some states, like Connecticut, are working towards regulating movie sound levels, but it is unclear if and how these regulations will be implemented without violating free speech rights.

What You'll Learn
Movie theaters don't have sound regulations
There are currently no regulations on sound levels in movie theaters. While there is an industry "standard" of 85 dB SPL, this is not consistently enforced, and there are no laws specifically targeting the loudness of sound in theaters. This has led to concerns about the potential impact on the hearing of both audience members and audio professionals.
The lack of regulation means that movie producers, studios, and directors are generating soundtracks with very high sound levels, which can be annoying and potentially harmful. In addition, the introduction of digital sound technology has made it possible to increase volumes to extreme levels without the distortion that was previously associated with analog sound. As a result, there is a growing debate among sound professionals about how to safely retain creative control over the mix.
Some individuals and organizations have called for legislation to regulate sound levels in movie theaters. For example, Connecticut has proposed legislation that would prohibit movie theater owners from showing movies or trailers with noise levels exceeding 85 decibels. However, there is also opposition to such regulation, with the Motion Picture Association of America (MPAA) arguing that it would violate the First Amendment right to free speech.
The MPAA also claims that regulating only movie theaters and not other loud events, such as rock concerts or sporting events, would be discriminatory. In addition, they argue that the issue of loud movie trailers has already been addressed through a voluntary agreement with the National Association of Theater Owners in 1999, which set a limit of 85 decibels for trailers. However, critics argue that this voluntary standard is not consistently enforced.
The lack of sound regulations in movie theaters presents a challenge, as both individuals who prefer louder sound and those who prefer softer sound need to be accommodated. While some have suggested allowing a peak sound level of 85 dB SPL rather than an average, it is clear that the current lack of regulations can be problematic and that finding a solution that satisfies everyone will be difficult.

There are OSHA laws on indoor noise levels
There are currently no regulations on sound levels in movie theaters. However, there are Occupational Safety and Health Administration (OSHA) laws that address indoor noise levels in workplaces. OSHA sets legal limits on noise exposure in the workplace to protect workers from hearing loss. These limits are based on an 8-hour time-weighted average (TWA) and are measured in decibels (dBA).
According to OSHA, exposure to noise levels above 85 dBA can damage a person's hearing. When employee noise exposures equal or exceed an 8-hour TWA of 85 dBA, employers are required to administer a hearing conservation program. This program includes monitoring employee noise exposure and providing hearing protection devices if necessary. OSHA also requires engineering or administrative controls when noise exposure exceeds 90 dBA as an 8-hour TWA.
In addition to the general industry standards, OSHA has specific regulations for construction sites and other worksites with impulsive or impact noise. For example, OSHA states that exposure to impulsive or impact noise should not exceed 140 dB peak sound pressure level. OSHA also provides guidelines for measuring noise levels and determining compliance with their standards.
While OSHA's regulations do not specifically cover movie theaters, cinema owners often follow the OSHA standard of 85 dBA as a suggested limit. However, there have been reports of peak noise levels in theaters exceeding this limit, reaching up to 133.9 dBA. The lack of regulation in theaters has sparked a debate among industry audio professionals, with some advocating for safer sound mixing practices and the inclusion of other loud events, such as rock concerts or sporting events, in the discussion.

Movie trailers are designed to be loud
There are no current regulations on sound levels for movie theaters. However, there is an "industry standard" of 85 dB SPL, which is often exceeded by movie soundtracks. The transition from analog to digital sound has made it possible to increase volume to extreme levels without distortion, and movie producers, studios, and directors are taking advantage of this to generate soundtracks at very high sound levels.
One notable sound effect is the "Bwah" horn blast from the Inception trailer, created by veteran composer Hans Zimmer. This sound has been repeated in numerous trailers since its debut, with editors slicing and dicing the simple sound to change its context and immediacy. Another example is the use of tribal chants in the trailer for The Dark Knight Rises, which was then imitated in Captain America: Civil War. Editors also like to use steady, booming drumbeats in action movie trailers, such as in Kong: Skull Island and The Lost City of Z.
In addition to sound effects, trailer editors also use compression to increase the impact of the trailer. This involves lifting all the sound levels to the higher end, creating a greater impact on the audience. While this may be effective in gaining attention, it can also cause irritation when the trailer is played at a much higher volume than the film, or when compared to programs with a wider dynamic range. Ultimately, the loudness of movie trailers is a deliberate choice by the filmmakers to capture the audience's attention and make their film stand out.

Movie sound can cause hearing damage
There are currently no regulations on sound levels in movie theaters, and this lack of regulation is a cause for concern. Movie theater decibel levels can reach unsafe levels, and exposure to loud noise can cause hearing damage. The recommended noise level is 85 decibels, but theaters often exceed this to enhance the audience's experience. This can have disastrous effects on the ears, causing hearing damage and even contributing to hearing loss.
The impact of noise on hearing depends on both the noise level and the length of exposure. At 85 decibels, eight hours or less is considered safe. However, as the sound gets louder, the safe exposure time decreases. For example, at 91 decibels, the safe limit is two hours, and at 100 decibels, noise can cause hearing damage in just 15 minutes.
The high volume in movie theaters can be particularly harmful to children, who may be more susceptible to noise-induced hearing damage. Lee Ann Burdick, director of the Russell J. Call Children's Center at Northeastern, highlights this concern, stating that if the volume is loud for adults, it could be even more damaging for children's ears.
The transition from analog to digital sound has also contributed to the issue of loud movie sound. Digital sound can be increased to extreme levels without distortion, allowing movie producers to generate soundtracks at very high sound levels. As a result, some films may have soundtracks set far above the suggested 85 dB SPL level, potentially causing annoyance and harm to hearing.
To protect against hearing damage, individuals can take precautions such as using custom earplugs or earmuffs, especially when attending movies with extended action scenes, which tend to have higher decibel levels. Additionally, individuals can measure the volume in movie theaters using decibel meter apps on their smartphones to make informed decisions about their hearing protection.

Movie sound levels vary by theater
Industry Standards and Regulations:
While there are no federal regulations specifically governing sound levels in movie theaters, the industry has established a standard maximum volume of 85 dB SPL (Sound Pressure Level). This standard is based on previous analog sound technology, which had a practical limit of 85 dB SPL before distortion occurred. However, with the advent of digital sound, it is now possible to achieve much higher volumes without distortion, and some movies have been reported to exceed this standard.
Individual Theater Policies and Practices:
Movie theater owners have the autonomy to adjust sound levels within their establishments. This discretion can lead to variations in volume across different theaters playing the same movie. Some theaters may prioritize delivering an immersive audio experience, resulting in louder sound levels. Conversely, other theaters may opt for more moderate volume settings to ensure comfortable listening for their patrons. Additionally, factors such as the time of day or the presence of a younger audience can influence sound adjustments.
Technical Considerations:
The transition from analog to digital sound has significantly impacted movie sound levels. Digital sound technology allows for extreme volume levels without the distortion previously associated with analog sound. This advancement has led to movie producers, studios, and directors creating soundtracks at very high sound levels. However, the lack of standardization in digital sound equipment and mixing practices can result in inconsistencies across different theaters. Additionally, technical issues or variations in equipment quality may contribute to differences in sound levels between theaters.
Customer Experience and Feedback:
Customer feedback also plays a role in shaping movie sound levels across theaters. Some patrons prefer louder sound levels for a more immersive cinematic experience, while others may find excessive volume uncomfortable or even harmful to their hearing. Theater owners and managers may adjust sound levels based on customer feedback to strike a balance between delivering a compelling audio experience and ensuring the comfort and satisfaction of their patrons.
In summary, movie sound levels can vary by theater due to a combination of factors, including industry standards, individual theater policies, technical advancements, and customer preferences. While there is no federal regulation mandating specific sound levels, the ongoing debate surrounding movie volume highlights the importance of balancing creative control with the protection of audience hearing health.
