What is Sound Pressure Level and how is it measured

The unit of pressure measurement is pascal (Pa) Note The term sound pressure may be preceeded by other noise measurement terms such as instantaneous maximum and peak (e.g. peak sound pressure). Sound pressure level (SPL) is the pressure level of a sound measured in decibels (dB).

OCCUPATIONAL NOISE SURVEY ATEnvirocare

Personal dosimeters tend to overestimate the noise exposure due to the possibility of reflections from the person and a range of measurement errors of /-2dB(A) are likely. Spot measurements at operator positions tend to underestimate noise exposure levels due to the difficulty of maintaining a hand held meter close to a moving operator s head.

OSHA Technical Manual (OTM) Section III Chapter 5

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.

At 500 meters (0.3 miles) away that sound pressure level drops to 38 decibels. In most places according to Keith Longtin of GE Renewable Energy background noise ranges from 40 to 45 decibels meaning that a turbine s noise would be lost amongst it. For the stillest most rural areas Longtin says the background noise is 30 decibels.
