Excessive noise levels can be a significant distraction while trying to talk to a client, and it can make it difficult to hear and understand what the other person is saying. It can also be frustrating and stressful for both the client and the bank employee. In addition to being a distraction, excessive noise level […]

Digital design and acoustics at the School of Architecture
The iterative process of professionals providing expertise to the design students, using a file-to-factory approach and continual feedback, proved an effective way of learning and producing fast and high-quality prototypes at the School of Architecture, Sweden. Collaboration between architects and acousticians, and between designers and other specialists In line with our continued effort to raise […]
The issue of invisible sound, commentary by acoustician Daniele Ponteggia
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 […]
Baltic-Nordic Acoustic Meeting 2022
On May 9-11 2022, Aalborg hosted the bi-annual Baltic Nordic- Acoustic Meeting (organized by the Nordic Acoustic Association), which this time is merged with the EUROREGIO (organized by the European Acoustics Association). The conference brought together academics, engineers, consultants, and other practitioners in the wide field of acoustics. Some of the really interesting presentations are […]
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 […]
Ventilation through acoustic ceilings – What is diffuse ceiling ventilation?
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 basics of room acoustics: Theory & terms
We at Acoustic Bulletin writes for both acousticians and sound enthusiasts of all types and levels of experience. This post is for anyone who is just entering the field of room acoustics. It contains only very simple and basic descriptions of the the main terms, but should provide enough detail to give you a firm […]
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 […]
