How do I choose a sound level meter?
How do I choose a sound level meter?
For you to assess hearing protectors the sound level meter needs to measure the LCeq (C weighted average sound level) or carry out Octave Band Analysis. Most integrating sound level meters will provide LCeq too, but you should check.
Is standard for sound level meter?
The current international standard that specifies sound level meter functionality and performances is the IEC 61672-1:2013. However, the reading from a sound level meter does not correlate well to human-perceived loudness, which is better measured by a loudness meter.
At what distance is noise levels measured?
Measurement should be taken 1 to 3 metres from source (not directly at the source). Particularly useful if noise is highly variable; it can measure equivalent sound level over a short period of time (1 minute).
How accurate are dB meters?
The tests also compared results for i-Phones and Android phones. OSHA requires noise measurement instruments to have an accuracy of +/- 2 decibels (dB). For unweighted sound level measurements, NoiSee, SoundMeter and SPLnFFT had mean differences within the +/- 2dB of the reference measurement.
What are the specifications of sound level meters and noise dosimeters?
Two critical specifications for sound level meters and noise dosimeters are frequency range and sound level range. Frequency range is the range of frequencies for which the meter maintains a constant sensitivity within defined boundaries.
What is NIOSH sound level meter (SLM)?
The NIOSH Sound Level Meter (SLM) app combines the best features of professional sound levels meters and noise dosimeters into a simple, easy-to-use package. The app was developed to help workers make informed decisions about their noise environment and promote better hearing health and prevention efforts.
What is a sound level meter and how does it work?
Sound level meters measure real-time sound and can have functions such as signal analysis, noise dose measurement, and different time and frequency weighting.
What is a Class 2 outdoor sound level meter?
The class 2 outdoor sound level meter PCE-428-EKIT, from the field of environmental measurement technology, is an optimal sound level meter for measurements at workplaces, construction sites, in traffic, airports, etc.
