Summary
Noise is measured in units called decibels (dB) which indicate the relative loudness of sounds in air as perceived by our ears. The Centers for Disease Control and Prevention and the National Institute for Occupational Safety and Health recommend that noise levels above 70 dB over a prolonged period of time can cause immediate harm to our ears, and that the NIOSH REL for noise is 85 decibels.

Summary
A decibel (dB) is a unit of measurement for sound, and A-weighted decibels (dBA) are an expression of the relative loudness of sounds in air as perceived by our ears. The Centers for Disease Control and Prevention and the National Institute for Occupational Safety and Health recommend that noise levels above 70 dB over a prolonged period of time can cause immediate harm to our ears, and that the NIOSH REL for noise is 85 decibels. HHF has used Decibel Meter Pro to record the noise levels of hundreds of New York City subways, showing that the average noise levels on all subway platforms and on all subway rides are between 72.5 and 76.5 dB and between 74.1 and 75.8 dB, respectively.

Summary
The chart gives examples of how loud some of the common tools and objects we may see (and hear!) in our life are.
Noise is characterised as 'unwanted sound'. This sound is measured in units called Decibels (dB) which tell you how loud something is and if the noise is loud enough to cause damage to hearing.

Summary
This article discusses the importance of using a decibel level chart to capture sound effects, and how gear affects field recordings. It explains that microphones are not designed to capture louder sounds, and that bit-depth is important for recording sound effects. It also provides a guide to gear capabilities, such as microphone maximum SPL, bit-depth, and self noise, to help readers better understand the capabilities of their equipment.
