The Challenge

dBx Acoustics has been working with HPA Architecture on the acoustic design of the Green Pastures Pentecostal Church in Ballymena, County Antrim, since 2013. Not only does the building contain a 4000 seater auditorium, it will have significant youth and educational facilities, as well as social space. This includes everything from classrooms to cafes, and from a sports hall and gym to smaller auditoria and recording and broadcast studios.



The Solution

As the scheme design approaches the tender stage, we have advised reverberation time throughout, as well as sound insulation between spaces. In particular, there is a need for significant sound insulation between the auditorium and adjacent spaces which are in simultaneous use – no small feat given the Client’s requirement to run the front of house PA at 112 dBA! We’re also working with the mechanical services consultant to control services noise both inside and outside the building.

We have also worked closely with the Local Authority to help them draft appropriate planning conditions for noise emissions from the site in order to ensure that there is no adverse impact on nearby residents – or on the housing proposed as part of the wider masterplan in future. Our noise impact assessment has been used to set noise emission limits against both BS 4142:2014 and BS 8233:2014, and has helped to define the sound insulation specification for the Auditorium roof and facades.

We’re excited to be involved with such a large scheme which will bring great new facilities to this community.
