    Be aware that if noise levels are high enough rotation could increase the chances of hearing loss in more workers. If there is a regular noise level of 90 dB for example a healthy worker in the area can rotate into an area with a 50-dB noise level without a substantial increase in risk of hearing loss.

  • What are decibels the decibel scale noise measurement

    Noise Measurement Units. When you measure noise levels with a sound level meter you measure the intensity of noise called decibel units (dB). A sound meter uses a display with a decibel range and resolution to approximate to the ear s dynamic range usually the upper range rather than the quiet part.

    Frequency analysis is not required when the purpose of noise measurement is to assess compliance with regulatory exposure limits or to assess risk of hearing loss. For such purposes the A-weighted noise level in dB(A) percent noise dose or time-weighted average (TWA) equivalent sound level is sufficient.

    Most of this noise is generated in the exciter section and amplified by following stages on out through the transmitter output stages. Some transmitters are worse than others in generating this broadband noise spectrum. (Some transmitters seem to be little more than a broadband noise generator.) The type of modulation also affects the noise level.
