Technical Specifications

Size:

Many size options are available; can accommodate anything from a solo musician to a large group, band or choir.
Typical internal ceiling height is 2300mm.

Performance:

Typical sound insulation performance;
Room to corridor would be circa DnT,w41dB, Room to room would be circa DnT,w54dB.
Third octave band sound transmission losses available on request, tested in accordance with ISO 140/4.

Flexibility:

Construction:

Modular 100mm thick panels are secured with full length ‘C’ or ‘L’ clip fixings.
Acoustically sealed base channel controls wall panel placement. Neoprene seals to the base of all MPR walls assist regarding the elimination of structure borne sound transfer.
Panel comprises of 1mm gauge solid steel outer skin and 0.7mm gauge perforated steel inner skin.
Powder coated panel finish; Light grey outer/satin white inner.
Ceiling panels are secured using an interlocking tongue & groove jointing arrangement.
Typical panel weight would be nominally 32kgs/m2.
Solid skin internal surfaces exist at all corner, power panel and inlet/extract ventilation panel locations.
Single leaf personnel acoustic engineered door has ¾ length, centrally located vision panel, locking hardware and thumb turn override. Steel construction with acoustic seals. Shallow 33mm threshold can be negotiated for wheelchair access.
Glazed acoustically engineered windows are available, for control room purposes, observation, security or to provide natural light.

Ventilation:

Integral fan unit and external vertical attenuated tract for extract air and external attenuated vertical duct for inlet air.
Nominally 4No air changes per hour will be achieved using a scavenge ventilation system, on the basis of providing 8 litres/sec per individual (room size dependent).
Acoustically isolated HVAC connections are also available.

Lighting:

Surface fixed lighting would comprise high frequency florescent unit/s, controllable from wall mounted switching via RCD.

Electrical Components:

No double socket, internal RCD with control switching on vertical trunking(as standard).
Additional sockets, data points etc are available within 3 compartment dado trunking.
Wiring to the associated internal services and external isolator etc would be by others.
All components are CE certified and comply with BSEN 9002 European wide directive.
Minimum clearance over room height to be a minimum of 150mm.
Minimum spacing of 50mm from walls and 250mm from adjacent MPR’s.
Supporting floor structures will accommodate the room loadings, be flat level and true.
Floor level tolerance provides a minimum flat and level surface of 3mm over 1000mm.
Ventilation of the room where the MPR is located is required.
Wiring to and from internal services to external isolators will be undertaken by others.
Installation service (if required) demands room to be cleared of furniture prior to the arrival of our installation team.
Site inspection carried out, by our Acoustic Engineer and acoustically trained staff, before delivery/installation schedule is agreed.

Options and additions:

Closure panels between and around MPR’s.
Sound isolating floating floors available.
Glazed acoustically engineered windows available, for control room purposes, observation, security or to provide natural light.
Additional sockets, data points etc are available within 3 compartment dado trunking.
Sound limiting devices available for fitting in accordance with BB93 and/or Health and Safety requirements.
