Rallying behind a rising motorsport star

An image showing rally driver Ashleigh Morris

Motorsport is incredibly exciting. Whether it’s the thrill of competitive circuit racing in Formula One, the raucous roar and desire for speed in drag racing, or the battle against the clock either off-road on a track in rallying, motorsport speaks to the thrill-seeker in everyone. We’ve recently teamed up with rally driver, Ashleigh Morris, in a sponsorship deal for the final races of this season, which has also allowed us to capture the noise levels from the driver’s seat.

Not every day’s a drag – measuring the noise levels of a drag racer

An image of drag racers, after their noise output levels had been recorded.

Cirrus Research recently welcomed the Wilson family to our headquarters in Hunmanby to help them with a very particular noise problem; they needed to ensure that their junior dragster conformed to Motorsport UK noise guidelines, and they reached out to us to help them. In this case study, we look at the backstory of the Wilson family and explain how we were able to measure the noise levels of a drag racer, demonstrating our adaptability and suitability to monitoring motorsport noise.

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 is reverberation time and how it is calculated?

What is reverberation time and how is it measured?

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, ceiling, windows or tables. When these reflections mix, a phenomeon known as reverberation is created. Reverberation reduces when the reflections Read More…

Calculate Reverberation Time (RT) with the new NoiseTools Module

Calculate Reverberation Time with the NoiseTools RT 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…
