Combination of Absorbers and Diffusers – An Experimental Study in a Classroom

This study provides information on how different acoustic treatments can be used to obtain different room acoustic qualities, and can be used to improve and fine-tune the room acoustic parameters for better speech and listening conditions in classrooms. The background overview The most common acoustical treatment in ordinary classrooms is a suspended sound absorbing ceiling. […]

Our Visual Focus (part 3) – Deafly Designed

What do modern human societies sound like? Have we neglected the soundscapes of human society, and how may our cultural focus on our sense of sight have affected how we design buildings? The World Health Organization (WHO) categorize noise as the most significant environmental health threat right after air pollution (1). This should also be […]

Is it really possible to predict the room acoustic values in a non-diffuse room?

We made acoustic measurements as part of a remodelling of our training area at our head offices during the different phases of the acoustic treatment in the refurbishment. This is outlined in a previous Acoustic Bulletin post which highlighted the need for wall absorbers to remove the flutter echos, thus reducing the reverberation time and […]

Reverberation room vs Anechoic Chamber

Here is a short film where our editor Juan Negreira demonstrates some aspects around the acoustic free field, and the broad range of acoustic dynamics which can be found between two acoustic opposites. This is a chance to experience and share difference between being inside a room coated with highly absorptive material versus in a […]

Designing out “Chinook” flutter echoes in speech communication rooms

In September, it was a pleasure to present a work in progress “Optimising the acoustic design for a multi-purpose room used for speech communication activities” at ICA 2019 in Aachen. One of our inhouse head office rooms recently remodelled to accommodate a mixture of training functions. The sound environment for a room designed for speech […]

Find out what a room can sound like – with the Ecophon Acoustic Calculator

Today almost all room acoustic calculations are based on the Sabine formula. Even though it is known that you often get different values when you compare calculations with actual measurements in a room. Therefore, Ecophon has developed a calculator in which the intention is to have more accurate acoustic values before measurements. The Ecophon Acoustic Calculator is […]
