Recording Studio Acoustics

SonaSpray acoustic decorative treatment corrects recording studio acoustic.

Noise reverberation is critical in designing recording studio acoustics.  Too much noise reverberation i.e reflected noise can distort recorded or transmitted presentations.

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.

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

Recording Studio Acoustics

Rain noise on roofs can be a problem when designing recording studio acoustics as with the new Warner Bros. Leavesden studios where Oscar Acoustics is installing 30,000m2 of SonaSpray K-13 for this reason.

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.

Octave-Band Sound Pressure Level

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.

Music Recording Studios

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

When Cold Play 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 floating ceiling system fixed with isolated rubber mounts restricting noise from travelling through the ceiling in the form of vibration.

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