Common Noise Levels

The Center for Hearing and Communication is proud to offer the Noise Center as a public service for people seeking information about the dangers of noise exposure and the steps they can take to promote a safer and quieter world.

Exposure to noise is the leading cause of hearing loss- not age. Repeat exposure to noise at a level of more than 85 decibels (dB) can result in permanent hearing problems. The good news: noise-induced hearing loss is preventable. The key is to minimize your exposure to noise and take appropriate action to protect your hearing when you’re in a noisy environment.


Check out this list of common environmental noise levels that surround us daily. 

Why do we care so much about unwanted noise?

  • In the short term, noise causes stress, and as most of us understand, stress is terrible for your health. In the long term, noise causes hearing loss—and hearing loss is also detrimental to your health.

  • Individuals and communities no longer accept that noise is a natural by-product of an industrial society. Grassroots activist groups address the issue of noise in their own communities. New Yorkers gave noise as the leading complaint to quality to the city’s life quality hotline.

  • Adults may be the ones to have the greatest concerns about and problems dealing with noise, but children can suffer just as much, and there may be no indication as such to their parents.

INAD 2023: April 26, 2023

All over the world, people, organizations, and governments

will commemorate the 28th Annual International Noise

Awareness Day (INAD) on April 26, 2023. The Center for

Hearing and Communication (CHC) founded this yearly

event in 1996 to encourage people to do something about

bothersome noise where they work, live and play.

  • Find a quiet space

  • Make sure you have handy wireless or wired headset or earbuds

  • This screening is intended for age 18 years and older

  • Although the screening is not a replacement for a hearing test, it is a great indicator as to where your hearing stands



Do you have a specific question or concern related to noise?

E.g., how to know if it’s harmful, controlling noise, protecting your hearing, or conducting your own noise awareness work. Your question may be answered in our facts and FAQ section. If not, contact the noise experts at CHC via the free Ask The Experts program, or call the Noise Center at 917-305-7810. If this is a complaint about noise from a neighbor, outside source, etc. please call 311.


FAQ: Protecting Your Hearing

People often avoid using hearing protection devices (HPDs) because of common misconceptions associated with the hearing protection. There are numerous options available in hearing protection that are easy to use and can help avoid a lifetime hearing disability. The following material is excerpted from The EARlog Series by Elliot H. Berger, Senior Scientist, Auditory Research, E-A-R-. 

Excuse: I don’t need hearing protection; I am used to the noise.

Response: Ears do not get used to noise – they “get deaf” (and unfortunately a deafened ear may often seem to get used to the noise). Repeated exposure to noise does not toughen ears nor does having an existing noise induced hearing loss prevent you from losing the hearing you have left. Although individual susceptibility to hearing loss from noise exposure varies widely, there are currently no standardized tests that can detect the more noise sensitive members of the population.

Question: I’ve already lost some or most of my hearing. Why should I have to wear hearing protection?

Response: The existence of a noise induced hearing loss does not protect one from further loss of hearing due to noise exposure. Initially hearing is damaged in the higher frequencies and as the unprotected exposures continue, this damage spreads to the lower frequencies, eventually affecting those essential to the understanding of speech (500 Hz to approximately 3000 Hz).


Although HPDs cannot restore a noise induced hearing loss, which by its nature is permanent and irreversible, they should prevent additional losses from being incurred.

Complaint: Hearing protectors are uncomfortable.

Response: HPDs are often uncomfortable initially, but hearing loss due to noise exposure is “uncomfortable” permanently. Like a new pair of shoes or glasses, hearing protectors do require a reasonable period of adjustment. Since not all hearing protectors adapt equally well to all head shapes and earcanals, it is important to give the employee the final choice in what he or she will wear. If after a couple of weeks of daily use the employee is still experiencing difficulties or discomfort, the protector should be resized and/or refitted, or another hearing protector should be issued.

Complaint: I can’t hear my fellow workers if I wear hearing protectors.

Response: When the ear is bombarded with high level sound, it overloads and distorts, reducing its ability to accurately discriminate different sounds. Wearing HPDs reduces the overall sound levels so that the ear can operate more efficiently. The effect is similar to the improved vision that sunglasses provide in very bright, high-glare conditions.

For those with normal hearing, HPDs will usually provide improved communications when sound levels are greater than approximately 85 dBA. For moderate to severely hearing impaired individuals, the situation is more complicated; for them, hearing protectors may not provide a communications benefit and actually be a liability. But, if these individuals do not  protect their hearing, they may suffer additional impairment, and then they will have even greater difficulty communicating regardless of noise level.

Question: Do earmuffs block out noise better than earplugs?

Response: No. The misconception that earmuffs are better than earplugs at reducing noise is partly due to the “bigger is better” school of thought. Actually, whether or not an earmuff or an earplug is better is dependent upon the device and user in question.

Question: Can earplugs cause ear infection?

Response: Based on our experience during the past decade, and information gleaned from consultation with experts in the field of otology and audiology, as well as data from an ongoing survey of U.S. industries, it appears that the likelihood of earplugs causing outer ear infections (otitis externa) is minimal. Although it would seem that placing a dirty or gritty foreign object in the earcanal could easily lead to irritation or infection, the data from existing HCPs [Hearing Conservation Programs} seem to indicate that the external ear is fairly resistant to such abuse. Nevertheless, cleanliness should be stressed and certain individuals, such as diabetics and those who are prone to infection, should be more carefully monitored.

Question: Can hearing protectors cause headaches, nosebleed, ulcers, insomnia or eyestrain?

Response: Headaches may be caused by an HPD (primarily circumaural devices) that fits too tightly, or is in some other way uncomfortable. The HPD should be resized, refitted or another device issued.

There are no known medical or physiological reasons why HPDs should be suspected of causing any of the remaining maladies listed above. However, when an employee voices such complaints, this indicates dissatisfaction with the HPD he is wearing, a misunderstanding of the need for its use, or a real health problem that has been mistakenly attributed to the use of the HPD. The best response will be a patient and accurate assessment of the situation and determination of the actual cause of the disorder.

Question: Can I use stereo earphones for protection against noise and enjoy the music at the same time?

Response: The foam earphones offer almost no protection. Even the circumaural device provides no more than approximately 20 dB of attenuation at high frequencies, and actually significantly amplifies sounds at some frequencies. This protection is inferior to that of a well designed, properly fitted HPD. Furthermore, these devices alone can generate equivalent noise exposures up to approximately 100 dBA.

Since these devices offer so little attenuation, a greater concern is that employees might turn up the music to mask (i.e., “drown out”) the factory noise. Products are available which have been specifically designed to offer adequate protection and at the same time play music or transmit voice communications. Although generally expensive, such devices are suitable for use, especially when they have built-in signal limiting circuitry so that they are not capable of presenting hazardous sounds to the ear.

Excuse: I don’t need to worry about losing my hearing since I can always get a hearing aid.

Response: Although eyeglasses can in most cases correct a vision problem to a nearly normal condition, it is a misconception that hearing aids can do likewise for a noise induced hearing loss. Correctable vision problems generally result from ocular distortions and not the loss of the optic nerve cells, whereas noise damage is due to destruction of the nerve (hair) cells in the  cochlea that enable us to hear. Hearing aids can restore the ability to detect and discriminate sounds to a certain extent, but when insufficient hair cells are present to receive the amplified sounds that the aid provides, the results are not fully satisfactory…and if wearing an HPD 8 hours/day is objectionable, will it be any more acceptable to wear a hearing aid (which feeds sound into the ear through an earplug like device) for all of one’s waking hours?
