Church Acoustics, Diffusion and Absorption

Church Acoustics can be one of the most difficult areas of acoustical design, due to the number of specific requirements of a church auditorium. Whether this is for amplified music, speech or for stage presentations (e.g. Choirs), the acoustic requirements vary significantly. In many old church buildings as in the old cathedrals of Europe there was no absorption but many examples of reflection and diffusion. Trying to create this effect with today’s audio technology and building design can be difficult, but by engaging a qualified Acoustic Engineer as well as using the correct product design and installation this can be achieved.

Recently City Life Church in Melbourne, Australia were having a number of problems , from the space being too dead at some frequencies and reflective at others. Working with Hanson and Associates of Melbourne, Sontext manufactured Acoustic Panels and together with curved diffusers as seen in the Fabric Covered Acoustic Diffusers by Sontextphotograph below. By using a combination of a sound absorbing insulation and a plywood face the Serenity Acoustic diffuser was developed. While the Acoustic performance of the diffuser is very important, equally as important is the aesthetic finish. Covered in Rim Trilogy 1 fabrics by Innova this gave a fashion and decorative finish.

Other areas of the auditorium that were treated were 100mm thick Serenity Acoustic panels at the side of the stage and 50mm thick Serenity Acoustic panels in the hallways. By working with the Acoustic enginnerer Sontext was able to deliver a fully installed solution for City Life Church and the results have been exceptional.

Sontext offer Diffusers, Reflective panels, Quadratic diffusers, Bass traps, Sound Absorbing Acoustic Panels, all tailored to suit the specifications of the Acoustic engineer and the Aesthetic requirements of an Interior Designer.
