Highway Speed Limit above 35 MPH – 84 dB(A). Perceptions of increases in decibel level. The list below gives you an idea of how noticable a change in decibel level will be to you: 1dB – Not noticable; 3dB – Noticeable to humans; 5dB – Clearly noticeable change; 10dB – About twice as loud; 20dB – About four times as loud While the 80-decibel level applies to noises that are farther away, your infant may hold toys close to his ears, which can be very harmful. Some toys can inflict as much as 120 decibels of exposure to your infant, which is the equivalent to hearing a jet plane take off, according to the American Speech-Language-Hearing Association.

Sound is measured in units called decibels (dB). The higher the decibel level, the louder the noise. On the decibel scale, the level increase of 10 means that a sound is actually 10 times more intense, or powerful. Required voice levels at distance.

Frequency.

For example, the 2005 Regulations require employers to take action to protect workers at levels of noise 5 decibels lower than in the 1989 Regulations and now require health surveillance (hearing checks) for workers regularly exposed above 85 decibels. Many thousands of people are exposed to loud noise at work that may be a risk to their hearing.

101-125 dB: 110 decibels and above is the level where other sounds can not truly be heard. Aircraft takeoff, trains, and quite loudly concerts would fall to the 110+ decibel level. 126+ dB: 125 decibels is where sound really begins to get painful. Now, you’re basically talking about weaponized audio. Then a "3-dB exchange rate" formula is applied, which means that for every 3 dB above 85 dBA, the maximum exposure time is cut in half. Noise levels above 140 dB are not considered safe for any period of time, however brief.
