2. Do Not Use Your Music Player For More Than 60 Minutes A Day. High decibels can produce hearing damage rather quickly, but decibels above 80 can produce hearing damage in a matter of hours. Give your ears a break from your earphones after 60 minutes of music listening. Your hearing health is worth it. 3.
The solution to these problems is the decibel scale. Here's how the decibel scale works. The level at which a sound becomes audible to a young, average, healthy ear is designated as zero decibels (0dB). 1. Every increase of 3 dB is a doubling of the sound pressure level (twice as many micropascals). A sound of 23 dB is twice as much energy as a sound of 20 dB. 2. Every increase of 10 dB is a tenfold increase. A sound of 30 dB is ten times as loud as 20 dB, and 100 times as loud as 10 dB. 3. Conversational speech is at about 60-70 dB; a whisper is around 20 dB. 4. The decibel scale is actually a pretty accurate representation of how the human auditory system perceives sound. In reality, a 40 dB sound is 100 times as loud as a 20 dB sound, but it seems twice as loud. Twice as loud as 20 dB is actuallly 23 dB, but it doesn't really seem that way.
