Sound Level Meters and Noise Dosimeters Information
Sound level meters and noise dosimeters are used in many kinds of sound and noise analysis including industrial safety, traffic and transportation noise quantification, and scientific noise measurement. They are frequently hand-held and battery-powered. Sound level meters measure real-time sound and can have functions such as signal analysis, noise dose measurement, and different time and frequency weighting.

Do you know of any disastrous mistakes that occurred due to the incorrect usage of sound level meters and noise dosimeters?
6 answers
Mistakes have been done in wrong evaluation of the Sound Rating of Partitions and basing decisions on the ' specifications' of the material, while the actual complete installation had 'defects' that seriously deteriorated the sound rating (flanking, unsealed gaps at joints, cutouts for services not properly sealed etc), this necessitates expensive repair works.
~Francois L, Builder/Contractor, Abu dhabi, United arab emirates
People exposed in high noise level area are becoming deaf and with severe mental trauma at least in mining, power and steel sector.
~Arun Gujral, Engineering Consultant, Dhanbad, India
Not disastrous but preoccupying: an inadequate evaluation of the noise in work places.

FeaturesTop
What would your design or feature "wish list" be for this product?
13 answers
A simple tool that can give fast and practical readings as you evaluate the sound rating of different partitioning systems in the construction. At present these evaluations are mainly done in laboratory conditions.
~Francois L, Builder/Contractor, Abu dhabi, United arab emirates
Remote monitoring (this would be used to determine acceptable levels at a distance, sometimes considerable) from the sound source.

Is there any advice you want to share with users to help them avoid common errors in selection or usage of sound level meters and noise dosimeters?
8 answers
Always check the weighting before the testing as some times the weighting changes back to the default settings.
~Research & Development, Melbourne, Australia
Buy only equipments with the functions that you will really use, avoiding an inadequate selection of parameters.
~Walter H, Physicist, Duque de Caxias - Rio de Janeiro, Brazil
Look also for the microphone capability and stability and for all self calibration with a suited instrument.

Yes should buy good quality reliable product to have safe work area for the workers with proper protection devices.
~Arun Gujral, Engineering Consultant, Dhanbad, India
Don't buy Radio Shack meters. They are horribly inaccurate in the lower frequencies (like 20 dB or worse).
~Ken D, Sound System Design & Operating Consultant, Portland, OR
The equipments have to proceed the requirements of IEC 61672.
~Walter H, Physicist, Duque de Caxias - Rio de Janeiro, Brazil
Buy the easiest to use and good portability.
~Jack R, Electrical Engineer - Construction Manager, Fairhope, AL
Look for all relevant facilities.
~Frej Jorgensen, Engineer, Hundested, Denmark
Must comply with IEC61672
