Lightweight, quick to construct, cost-effective, compact and able

to achieve high levels of fire resistance and acoustic insulation.

Non-load bearing High Performance Wall, constructed from USG Fiberock facings on Speedline metal studs, offer considerable advantages over traditional heavy masonry construction.

Partitions built using Acoustic Stud are constructed in exactly the same way as those built using standard C Studs. All existing track sections can be utilised with Acoustic Studs and Fiberock board fixing centres will be exactly the same.

Attention to detail is essential.Care must be taken in construction to ensure a soundproof structure performs to its maximum capability. Sound - like water, light or air willfind the smallest crack and expose it asa weak point, the structure should bebuilt as if it needs to be waterproof.

Building Regulation Requirements

Dwellings and Residential Units

In respect of dwellings, extracted from Approved document E (2003 Edition) this shows the general requirements for sound reduction in structures between dwelling units to meet section E1.

Requirements in Hospitals

This is covered by Health Technical Memorandums HTM 56 HTM 2045.

These require different levels of sound reduction based upon the usage of adjoining rooms, similar to how BB93 governs schools. The required performances range from 38dB to 53 dB.

Simply read along to match the 2 purpose rooms to determine the requirement for sound reduction between those rooms.

Consulting Room / Examination Rooms / Treatment Rooms / Speech Therapy Rooms / Offices / Seminar Rooms / Single bed wards / Multi bed wards / Day rooms / Nurseries / Toilets and Bathrooms / Utility Rooms / Ward Pantries

Requirements in Schools

Approved Document E of the Building Regulations states in respect of Acoustic Conditions in Schools:

“The normal way of satisfying Requirement E4 will be to meet the values for sound insulation, reverberation time and internal ambient noise which are given in Section 1 of Building Bulletin 93 ‘The Acoustic Design of Schools’

In respect of sound reduction this is determined by making reference to the appropriate table in BB93 and comparing the Activity noise in the source room with the Noise Tolerance in the adjoining receiving room to determine the sound reduction required.

The table is reproduced in simplified form below. To determine the required sound reduction:

  1. Look up Table 1 to check the Activity noise level in the source room (where the sound originates)
  2. Look up Table 1 to check the Noise Tolerance level in the receiving room (the room that needs the sound reduction)
  3. Read across table 2 to determine the actual sound reduction required in dB.

e.g If you wanted to determine the required sound reduction from a Music Classroom to an adjacent Art Room; Table 1 lists the Activity noise level in the music classroom as Very High, and the Noise Tolerance level in the Art Room as Medium. Cross reference these in Table 2 shows a 55 dB sound reduction required.
