This is a little louder than a normally humming refrigerator, which is typically around 40 decibels, and slightly quieter than normal talking, which is around 60 decibels. This measurement is known as maximum sound pressure level (SPL). You can use a sound level meter or a sound level meter app to measure noise levels. That tops out at 96.33 dB. The contours demonstrate that our ears become less sensitive at lower frequencies. The effect of lower noise levels over long periods is the same as louder noise levels over a shorter period. A whisper is between 20-30 dB. A sound that seems loud in a quiet room might not be noticeable when you are on a street corner with heavy traffic, even though the sound intensity is the same. For example, ten violins would sound only twice as loud as one violin. This is a difficult question to answer because it depends on the environment in which the sound is heard.
