Acoustic design principles

British Standards, EN and ISO Standards are often difficult to interpret, and frequently do not offer succinct design procedures that may be used to implement the methods they describe. In this paper, Jack outlines the Apex approach to organising calculations around the acoustic design issues.  The full paper is available to download below, as is the poster above in pdf format.

You can read a more detailed description of the typical method used to calculate facade sound insulation here.

We are working to develop a method to determine a pA erformance specification for facade elements for any incoming noise spectrum.  The initial development was presented at the IOA 2016 conference, but watch this space for further developments, and get in touch if you would like to discuss this.

Acoustics of timber frame & light guage steel frame constructions

We have researched the acoustics of framed constructions in great detail; Richard Hinton we have presented on this at the CIAT Yorkshire branch CPD day, see more information here.

Flanking sound in curtain walling

Following an extensive review of recent academic literature on flanking sound in curtain walling, Nick Conlan presented by far the most highly rated paper at the conference, from the feedback” the IOA received.  This makes accessible the sometimes difficult-to-understand flanking paths in curtain walling, revealing the performance of the different elements in isolation as well as how this changes as the systems are built up.  Read more about Nick’s presentation here.

Flanking sound in steel-concrete composite floors

Building on her Award-winning Diploma project, Beth Paxton developed her work on calculating flanking sound transmission in steel-concrete composite floors.  Her peer-reviewed paper was well received at the International Congress on Sound and Vibration, ICSV24, July 2017 in London.  You can download the paper and slides here.

Sound insulation measurements in non-diffuse rooms

Some of our classroom research interest comes from the discovery that non-diffuse rooms may give rise to issues with many types of measurements commonly undertaken by acoustic consultants. One aspect of this is the influence of non-diffuse sound fields on sound insulation measurements.
