What’s the difference between a sound level meter and a noise dosimeter?
I’m relatively new to the world of acoustic measuring and noise measuring equipment, and one of the very first questions I found myself asking was “what’s the difference between a sound level meter and a noise dosimeter?” Thankfully, the distinction is relatively simple and a complete novice like me can get to grips with it. So if you’re looking to Read More…
What’s causing noise pollution in offices?
An interesting study has emerged this week that points to a big increase in the levels of noise pollution in offices, and it’s all thanks to the popularity of open plan office spaces.

What is reverberation time and how is it calculated?
One of the most common questions we get asked is about reverberation time. So, we thought we’d provide an answer! What is the reverberation time of a room? Reverberation time is the time required for the sound to “fade away” or decay in a closed space. Sound in a room will repeatedly bounce off surfaces such as the floor, walls, Read More…
Calculate Reverberation Time (RT) with the new NoiseTools Module
Introduction to the Reverberation Time Module We’re pleased to announce the release of our new NoiseTools extension module which allows for the calculation of reverberation time in accordance with ISO 3382-2:2008. Using information measured using a suitable Optimus Sound Level Meter, the module allows the calculation of RT60, RT30 and RT20 values from either an interrupted or impulsive noise source. The module also Read More…
