Noise level meters are specialized sound level meters designed to measure unwanted sounds and compare them to established limits. These meters often take the form of either noise dosimeters or noise monitoring stations. Noise dosimeters are wearable devices that measure an individual’s noise exposure over a set period, commonly used in occupational health assessments to ensure safe noise levels. Noise monitoring stations are fixed installations designed for long-term, continuous measurement and logging of ambient noise. These stations are frequently used in environmental monitoring projects and have the capability to transmit data remotely for analysis.
Organizations like ISO, IEC, and ANSI all use the term “sound level meter” as their standard name. Professionals in the field tend to use this term. However, non-professionals may use the terms “sound” and “noise” interchangeably and may refer to outdoor noise monitors as “noise meters.” It is important to note that these terms may not accurately describe the device’s capabilities or accuracy.
