 SOUND SYSTEM SERVICES
In conference centres, auditoria, sport centres and halls and exhibition spaces, speech intelligibility and musical
clarity are of the highest importance. Vipac is involved with the design, specification and commissioning of sound
systems ranging from simple public address systems to large sports venue facilities. Client needs are reviewed
under consideration of the likely usage, leading to the preparation of a technical specification for the sound
system, review of tenders, and on-site commissioning. Critical requirements include the achievement of the absolute
sustained sound level with no clipping, uniformity of coverage, and an optimal frequency response covering the
range from 20Hz to 12,000Hz. Other issues considered are channel separation, distortion, signal-to-noise ratio
and direct-to-reverberant ratio.
Vipac is also involved in the specification and installation of State-of-the-Art Digital Reverberation Enhancement
Systems for venues wishing to extend the envelope of use whilst bounded by architectural conditions.
