Dangerous Decibels How Loud is Too Loud

Exposure Time Guidelines Accepted standards for recommended permissible exposure time for continuous time weighted average noise according to NIOSH and CDC 2002 For every 3 dBAs over 85dBA the permissible exposure time before possible damage can occur is cut in half

Safety and Health Topics Occupational Noise Exposure

Noise is measured in units of sound pressure levels called decibels named after Alexander Graham Bell using A-weighted sound levels dBA The A-weighted sound levels closely match the perception of loudness by the human ear

Common environmental noise levels CHC

Common environmental noise levels How loud is too loud Continued exposure to noise above 85 dBA adjusted decibels over time will cause hearing loss The volume dBA and the length of exposure to the sound will tell you how harmful the noise is In general the louder the noise the less time required before hearing loss will occur

decibel levels for mineral processing mineral processing plant offers 12218 processing conveyor products About 22% of these are conveyors A wide variety of processing conveyor options are available to you such as stainless steel aluminium and metal

Acceptable dB A Noise Level Engineering ToolBox

Acceptable noise dB A level at some locations Related Topics Acoustics Room acoustics and acoustic properties decibel A B and C Noise Rating NR curves sound transmission sound pressure sound intensity and sound attenuation Related Documents EPA Protective Noise Levels The noise level should not exceed certain values to protect public health and welfare


If noise cannot be controlled to an acceptable level at the source attempts should then be made to control it at some point during its propagation path that is the path along which the sound energy from the source travels

OSHA Technical Manual OTM Section III Chapter 5

The C-weighted scale is also an acceptable option for octave band analysis because in the range of most workplace noise level measurements unweighted sound level measurements are less than 1 dB higher than the corresponding C-scale measurements
