Safe listening time depends on the loudness of the sound, not just the duration. Higher sound levels significantly reduce the amount of time the ears can tolerate exposure without damage.
At 80 dB, sound exposure is generally considered safe for up to 8 hours. At 85 dB, safe exposure drops to about 4 hours. At 90 dB, it decreases to roughly 2 hours, and at levels above 100 dB, safe exposure may be limited to only minutes.
Because perceived loudness can be misleading, measuring sound levels and adjusting exposure time accordingly is the most reliable way to protect hearing. Taking listening breaks and reducing volume when possible further lowers the risk of noise-induced hearing loss.
