Line Source – What is It?

The behaviour of sound waves emitted by a long, linear source is referred to as line source sound propagation. In this instance, sound waves emanate from the source along a line or narrow segment, as opposed to a single …

Point Source – What is it?

The behaviour of sound waves emanating from a singular, localised sound source is referred to as point source sound propagation. In this instance, sound waves emanate from their source in a spherical or nearly spherical pattern.

When a sound is …

Mass Law – What is It?

The mass law, also known as the mass-air-mass law, is an acoustics principle that defines the relationship between a partition’s mass and its ability to block or attenuate sound transmission. According to the mass law, the sound transmission loss …

Flanking Sound – What is it and how can we help reduce it?

Flanking noise transmission, is an acoustics phenomenon that occurs when sound energy bypasses or circumvents a primary sound insulation barrier via alternative paths. Sound waves can travel through adjacent structural elements, such as walls, floors, ceilings, ducts, and other …

Reverberation Time and How to Measure It

Reverberation is the continuation of sound in an enclosed space after the source of the sound has ceased. Multiple reflections of sound impulses from the surfaces of the room, such as the walls, floor, and ceiling, produce reverberation. These …

Why We Love Acoustics – and further reading

Acoustics is a fascinating subject for various reasons, if you’re not already interested, here’s a few points that may change your mind, with a nudge towards some supporting reading

Sound Science: Acoustics enables us to dive into the underlying concepts …

Blog-tastic

Prepare for “bloggergeddon”.

Since we’ve been slacking on social media and website updates, the team has decided to go all out for the next 33 weeks by writing blogs.

To be exact, each week will include 33 new blog posts on …
