MUIC & ACOUTIC – HEARING HEALTH & MUIC EDUCATION CALCULATOR
Hearing Damage Time
A precise tool.
What is the Hearing Damage Time & How does it work?
Hearing damage can occur due to prolonged exposure to loud sounds, measured in decibels (dB). The louder the sound, the less time it takes for hearing damage to occur. The Noise-Induced Hearing Loss (NIHL) is a common issue among musicians and people who work in noisy environments.
T = frac{80}{SPL – 80}
T = Safe exposure time in hours
SPL = Sound Pressure Level in decibels
SPL = Sound Pressure Level in decibels
The formula above helps estimate the safe listening time based on the SPL level. For example, at 90 dB, the safe exposure time is approximately 8 hours.

Frequently Asked Questions
What is the formula for calculating safe exposure time?
The formula used is T = 80 / (SPL - 80), where T is the safe exposure time in hours and SPL is the Sound Pressure Level in decibels.
How long can I safely listen to music at 90 dB?
At 90 dB, the safe exposure time is approximately 8 hours.
What is Noise-Induced Hearing Loss (NIHL)?
Noise-Induced Hearing Loss (NIHL) is a common issue among musicians and people who work in noisy environments, caused by prolonged exposure to loud sounds.
How does sound pressure level affect hearing damage?
The louder the sound (higher SPL), the less time it takes for hearing damage to occur. The formula helps estimate safe listening time based on SPL levels.
What is the safe exposure time at 100 dB?
At 100 dB, the safe exposure time is approximately 4 hours.
Can I listen to music at 120 dB safely for a long time?
No, listening to music at 120 dB can cause hearing damage very quickly. The safe exposure time at this level is only about 15 minutes.
How does prolonged exposure to loud sounds affect hearing?
Prolonged exposure to loud sounds can lead to permanent hearing loss, tinnitus, and other auditory issues. It's important to protect your ears with earplugs or take regular breaks when exposed to high SPL levels.
