Recording Studio Acoustics

SonaSpray acoustic decorative treatment corrects recording studio acoustic

Recording studio acoustics are critical to the quality of sound. Too much reverberation ie reflected noise can distort recorded or transmitted presentations as microphones may pick up a sound more than once with a delay in between.

SonaSpray decorative finish applied to ceilings and/or walls absorbs noise instead of reflecting it [as with hard surfaces] resulting in the correct recording studio building acoustics.

The absorption coefficients of the range of finishes at various thicknesses are listed on our website, alternatively we can assist with acoustic calculations.

Rain noise on roofs can be a problem when designing recording studio acoustics. Acoustic laboratory tests on a thin [26guage] corrugated steel roof sprayed with 50mm of SonaSpray K-13 to the underside then heavily rained upon showed the following noise reductions.

Frequency Hz	63	125	250	500	1k	2k	4k	8k	dBA
Ceiling only Sprayed	6	7	8	6	11	14	16	16	9
Ceiling & Walls Sprayed	7	7	13	15	25	31	34	40	18
Octave-Band Sound Pressure Level

CNN use SonaSpray K-13 in recording studios around the world including the central London studio [as photo].

SonaSpray K-13 is applied to the profiled studio ceiling in the chosen colour of dark silver grey. This controls the recording studio acoustics and gives maximum headroom for the studio equipment.

SonaSpray is:

An acoustic decorative absorber of noise applied to almost any surface
Available in a range of finishes from textured to smooth
Through coloured and available in a range of colours
Fire rated to BS476 Class 1 to part 7 and Class 0 to part 6
Lightweight; SonaSpray K-13 at 25mm thick weighs 1.8kg/mtr2

The test states: The sound level reductions bought about by treating the ceiling appear to be related primarily to damping of structural vibration by SonaSpray K-13, and secondarily to damping of sound inside the enclosure. The treatment of the walls further damps the sound inside the enclosure, by greatly increasing the average sound absorption coefficient of the enclosure interior surfaces.

Recording studio acoustics also sometimes require a solution to a different noise problem i.e. noise transmission through walls floors and ceilings:

When a major touring band decided to take a break to record a new album they commissioned a new purpose built recording studio with living quarters in a secret location. There was concern of noise being transmitted through the roof and being a nuisance to neighbours. The builder filled the ceiling voids with mineral wool slab but this achieved only minimal improvement to the recording studio acoustics.

The builder contacted Oscar Acoustics to install their SonaCel isolated ceiling system, proven in installations across Europe.

SonaCel is a ceiling system fixed with isolated rubber mounts preventing noise from travelling through the ceiling in the form of vibration.

Sonacel solved the problem and the band free to record. SoaCel on our website.
