A “decibel” is the unit to measure the loudness of sound. Decibel levels for each item shown in the graph may vary.
If you need to raise your voice to be heard an arm’s length away, the noise is probably loud enough to damage your hearing.
How Long Is Too Long? The red bar below shows how long it takes for a particular sound level to become dangerous to the human ear. For example, a chain saw has a sound intensity of about 109dB. Without proper hearing protection, running a chain saw for only 2 minutes can cause hearing loss!
112 dB 109 dB 106 dB 103 dB 100 dB 97 dB 94 dB 91 dB 88 dB 85 dB
