Acoustics means beauty…but why is so much ugliness still around? Today there is a high possibility that you walk into a fancy restaurant, gym, swimming pool, museum, or sports hall and experience all kinds of acoustical defects. I often think about how architects, designers, and even landlords do not consider acoustics. Sometimes things are planned […]

Soundscape Attributes Translation Project (SATP)

The following article on the SATP project courtesy of Dr. Francesco Aletta, at UCL via Ph.D. Candidate Ela Fasllija at Bilkent University. Soundscape  Sounds in cities and built environments are often measured as noise in terms of decibel levels. Yet the human perception of soundscapes is often overlooked. Soundscape opens up the possibilities of managing […]

Thermally Activated Building Systems (TABS) and acoustics

Sustainable building practices are here to stay and the number of building projects involving Thermally Activated Building Systems (TABS) is growing rapidly. However, from an office worker’s perspective, exposed concrete walls and ceilings create acoustic environments where it’s virtually impossible to communicate and concentrate. This detailed TABS Knowledge Guide explains how acoustic ceiling coverage impacts cooling […]

Designing a holistic indoor environment can be challenging. It will often entail several compromises between quality of different aspects of well-being. It is extremely rare that a solution comes along that both enhances indoor comfort, reduces complexity of design while also saving money and lowering emissions. It definitely is extremely rare, but it happens. Diffuse […]

Nuanced room acoustics: Technical discriptors

Room acoustics is more nuanced than what is specified in most national requirements and regulations. If you, for example, wish to create a good sound environment in an open office environment, it is often better to consider multiple parameters and not merely the absorption area or reverberation time. The four primary technical basic terms that […]

The soundscape design pyramid: A design aspect hierarchy model

There are many factors contributing to the quality of a sound environment. Especially in complex rooms  like open offices, hospitals and learning environments. It is therefore important to have a clear understanding of how the different aspects of a design should be prioritised in relation to each other to ensure a high-quality outcome. Failing to […]
