Knowledge of the relation between people’s preferences and room acoustic parameters is critical for choosing the correct acoustic treatment and for creating good sound environments for people. In the frame of a PhD, people’s preferences regarding different acoustic environments were investigated. Their judgments were related to various room acoustics parameters. The results from the study […]

Navigating Unique Challenges in South African Acoustic Design
Unique Challenges Imagine stepping into the unique challenges as a project acoustician in the bustling heart of Johannesburg, South Africa. Your mission: to ensure the acoustic conditions of a forthcoming office building that will grace the trendy business district in three years. While the architect’s vision is crystal clear, and an array of documents and […]
Research and Development in Acoustics at Ecophon, EIAS 2023
In May 2023, it was again time for EIAS, Ecophon International Acoustics Seminar. We were utterly proud to once more host an event, focusing on development in room acoustics AND sharing a great time with some of the brightest minds within the field of acoustics. A bit more than 200 guests and 25 speakers from […]
Hungary’s Journey Towards Standardization in Room Acoustics: An Interview with Csaba Huszty
Standardization in Room Acoustics Room acoustics and electroacoustic systems are critical components of building design that can impact the quality of sound and speech intelligibility in various environments, from concert halls to classrooms and offices. In Hungary, the journey towards standardization in this area began over a century ago, but it wasn’t until 2020 that […]
Office noise increases stress hormone levels in blood plasma
Why this study? Valtteri Hongisto stated that there are no previous studies which have investigated the effects of office noise on the stress hormone levels (concentrations in the body) using the most precise and real-time method: i.e. blood sampling. Also a questionnaire was used to evaluate the effect. 100 person participated in the study and […]
Designing for Acoustic Satisfaction in Open Plan Offices: EIAS Presentation by Jack-Harvie Clark
Jack-Harvie Clark demonstrated that the perception of the acoustic environment is influenced by numerous factors. Working on room acoustics alone can help reduce annoyance caused by noise. Achieving acoustic satisfaction necessitates considering many additional factors that extend beyond room acoustics. Dissatisfaction with noise levels kills productivity Jack Harvie-Clark outlined at the beginning of this talk […]
Practical implications of acoustic design of open plan offices according to ISO 22955:2021: Insights from Juan Negreira’s presentation at EIAS 2023
The design of open plan offices has become a subject of intense scrutiny in recent years. At EIAS, in a presentation by Juan Negreira the practical implications of ISO 22955 for open plan office design were discussed, shedding light on the important considerations and best practices. The role of acoustics in offices At the outset […]
Listening tests: linking objective room acoustic parameters with subjective human perception
Daniel de la Prida from Carlos III University in Madrid presented about his study into listening tests. He focussed on tests that can be used for linking objective room acoustic parameters with subjective human perception. Such tests have been in use for many years. However, different research usually employs different test protocols, with different operational […]
The sound of absorption – an experience!
How would you explain the experience of good sound absorption in a room? To truly understand the value of better acoustics you need to experience it firsthand. This is why we have built two identical rooms with different absorption in our showroom Ecorama at the Ecophon headquarters in Hyllinge, Sweden. Here you can experience the […]
Classic Acoustics and Psychoacoustics – Similarities and Differences
Right after the grand opening of EIAS 2023, it was time for Alice Hoffman Senior Acoustician, PhD from Brekke and Strand, to make her entrance. She took us on a journey to see how Classical Acoustics can be compared to Psychoacoustics. Her own thoughts on this are that it often seems to be a lot […]
