Protecting Your Hearing
Introduction
Whatever your plans after graduation, you owe it to yourself and your fellow musicians to do all you can to protect your hearing. Certain behaviors and your exposure to certain sounds can, over time, damage your hearing. In most cases, noise-related hearing loss doesn’t develop overnight but happens gradually.
If you’re serious about pursuing a career in music, you need to protect your hearing. The way you hear music, recognize and differentiate pitch, and play music are all directly connected to your hearing.
Noise-induced Permanent Hearing Loss
The ear is made up of three sections, the outer, middle, and inner ear. Sounds must pass through all three sections before signals are sent to the brain. When a loud noise enters the ear, it poses a risk to the ear’s inner workings. A very loud sound can actually dislodge the tiny bones in the middle ear causing conductive hearing loss, which involves a reduction in the sound level experienced by the listener and a reduction in the listener’s ability to hear faint sounds.
Loud noises can send excessive sound levels into the inner ear, or cochlea, where tiny hair cells transmit sound waves to the brain. When a loud noise enters the inner ear, it can damage these hair cells, impairing their ability to send neural impulses to the brain causing permanent hearing damage.
The severity of noise-induced hearing loss depends on the severity of the damage to these hair cells and is related to the length and frequency of a person’s exposure to loud sounds over time. Because noise-induced hearing loss is painless, you may not realize that it is happening at first, but your hearing loss may eventually affect your ability to perceive both speech sounds and music. These hair cells in your inner ear cannot regenerate; any damage done to them is permanent.
According to the American Academy of Audiology, approximately 36 million Americans have hearing loss. One in three developed their hearing loss as a result of exposure to noise.
Noise-induced Temporary Hearing Loss
It is important to note that not all noise-induced hearing loss is permanent. Sometimes, after continuous, prolonged exposure to a loud noise, we may experience what’s called “noise-induced temporary hearing loss.”
During temporary hearing loss, known as Temporary Threshold Shift (TTS), hearing ability is reduced. Outside noises may sound fuzzy or muted. Normally, this lasts no more than 16 to 18 hours, at which point your hearing levels will return to normal. Often during this Temporary Threshold Shift, people will experience tinnitus – a medical condition characterized by a ringing, buzzing, or roaring in the ears – that may minutes but it can also span several hours (or, in extreme instances, last indefinitely). If you experience a series of temporary hearing losses, you experience permanent hearing damage in the future.
Noise Levels and Risk
Most experts agree that prolonged exposure to any noise or sound over 85 decibels (dB)* can cause hearing loss. The longer you are exposed to a loud noise, the greater the potential for hearing loss. Additionally, the closer you are to the source of a loud noise, the greater the risk that you’ll experience some damage to your hearing mechanisms.

FACT: Approximately 50% of musicians have experienced some degree of hearing loss.
Mindful listening
It’s important to think about the impact noise can have on your hearing health when you:
- Attend concerts.
- Play your instrument.
- Adjust the volume of your car stereo.
- Listen to ampplified music.
Here are some simple ways to test if the music is too loud. It’s too loud (and too dangerous) when:
- You have to raise your voice to be heard.
- You can’t hear someone who’s three feet away from you.
- The speech around you sounds muffled or dull after you leave a noisy area.
- You experience tinnitus after you leave a noisy area.
Basic Hearing Protection for Musicians
As musicians, it’s vital that you protect your hearing whenever possible. Here are some simple ways to reduce your risk of hearing loss:
- When possible, avoid situations that put your hearing health at risk.
- Refrain from behaviors which could compromise your hearing health and the health of others.
- If you’re planning to be in a noisy environment for any significant amount of time, try to maintain a reasonable distance from the source of the sound or noise.
- When attending loud concerts, be mindful of the location of your seats. Try to avoid sitting or standing too close to the stage or to the speakers, and use earplugs.
- Keep the volume of your music and your listening devices at a safe level.
- Remember to take breaks during a rehearsal. Your ears will appreciate the quiet time.
- Use earplugs or other protective devices in noisy environments and when using noisy equipment.
