Radio Studio Acoustics

Having purchased new radio station equipment, it would be disappointing if you didn’t consider your studio acoustic treatment and your broadcasts are let down by noise interference. Imagine trying to broadcast a clear, crisp sound from the middle of the office or hearing your presenters voice echo as the room lacks substance. The two critical factors for a studio of any type are isolation and internal reverberation.

This is why we broadcast from specially treated studios. Regarding studio acoustic treatment, you have a few options:

· Do nothing (not recommended!)

· If the shell or structure of your studio is suitable, add special door & window sets & internal acoustic treatment.

· Build new studios, using specialist tried and tested designs and construction methods.

· Install modular studios

Isolation

Isolation refers to the extent to which sounds outside the studio reach the inside. If your studio is on a flight path or next to a busy main road, acoustic isolation will be far more of a problem than if you are located in the countryside.

You don’t want interfering sounds to be picked up by the sensitive studio microphones and broadcast to your audience! You also want to prevent sounds from one studio spilling into the adjacent ones.

For best isolation you need thick walls – the more mass the better, with solid floors and ceilings – ideally concrete. Doors and windows are weak links, and special acoustic door and window sets should be installed by professionals.

Reverberation control

Reverberation refers to the amount of ‘echo’ you can hear within the studios themselves. An extreme example of this is a bathroom, which is referred to as having a very ‘live sound’. Control of reverberation is achieved using acoustically absorbing materials fixed to the walls and in some instances the ceiling.

You do not want your presenters to sound like they are broadcasting from a bathroom – this is not a pleasant listening experience!

The modular approach

There are many advantages of the modular approach:

· Construction is very quick, with the minimum of mess and disruption.

· Floor loading is far less than using traditional block-work methods.

· The levels of isolation are more guaranteed compared to the traditional approach, which can be very variable and often disappointing.

· It is possible to de-mount the studio and relocate it -impossible with conventional construction methods.

Clyde Broadcast 'Quiet Zone' Studio - Studio Acoustic Treatment

‘Quiet Zone’ Acoustic Booth – Exhibited at BVE, London 2017

Clyde Broadcast ‘Quiet Zone’ Acoustic Booths

Clyde Broadcast ‘Quiet Zone’ studios have a Weighted Sound Reduction Index of 40dB, and an average reverberation time of 400mS, ideal for radio applications in all but the noisiest of environments.

They are constructed from 600mm wide modules, which can be used to create a wide range of different room sizes, up to a maximum of approximately 5m x 5m.

Acoustic door and window sets are finished in American oak and carpet tiles are normally dark grey. Internal walls are finished in light grey and wall mounting acoustic panels are available in a choice of colours.

As standard each studio has a single door and window, though additional windows (and doors) can be specified.

Booths have low noise fans, and if air-conditioning is required this is normally installed locally. Low voltage track lighting and wall trunking is standard.

Floating floors can also be supplied if required.

Installation

Installation of a single room typically takes our team two days and we recommend that acoustic panels are installed AFTER the studio equipment, to allow fine tuning.

Acoustic components

For clients looking to treat existing studios and reduce reverberation, we recommend Clyde’s range of Acoustic Panels. These are available in a wide selection of colours and are available in two designs; WFAP (Wide Frequency Acoustic Panels) and LFAP (Low Frequency Acoustic Panels).

Sizes are 1200mm x 600mm. This allow panels to be positioned around radiators, alcoves and furniture. Panels are easy to install and typically between half and two thirds of the wall area needs to be covered.
