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 […]
Revision of CSN 73 0527 -The Czech Acoustic Standard
The importance of keeping standards relevant and up to date It is indeed important to periodically revise and update acoustic norms. This can take into account for developments like; advancements in technology, changing usage patterns, and evolving needs in indoor environments. As technology and audio-visual systems continue to advance, how we use and experience indoor […]
Acoustics and WELLbeing: the WELL Building Standard
Building standards often consider the performance of a building, including energy efficiency, water consumption and material usage. But what about the occupants? An environmentally friendly, well-built building provides no guarantees that their needs will be considered, even when certified in most cases. Unless it has a WELL Building Standard certification, that is, which considers thermal […]
New Finnish acoustic standard paves the way
Finland paves the way for clear and science-based guidelines worldwide, with its revised standard for acoustic environments in buildings. Developed by the country’s leading acousticians, the standard is established in the business and among policymakers. In 2017, Finland’s Ministry of the Environment issued a decree on the Acoustic Environment of Buildings. Several parts of the […]
There’s more to sound absorption than just the acoustics
Deciding which sound absorbing product to choose for a building used to be a fairly simple business. Assessing trade-offs between acoustic performance, design and budget were the primary considerations. But now we know that every product in a building has an additional cost for the indoor and outdoor environment. So it has become imperative that […]
Additional acoustic treatment in a bank hall – a case study.
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 […]
Great presentation of ISO 22955 at Internoise
Conference proceeding by Michel Batista: Acoustic assessment of an open-plan office environment against the newly published ISO 22955 acoustic parameters New ISO 22955 for open plan offices was a topic of a few research papers at Internoise. Michel Batista from Subsonic Designs showed interesting examples of in-situ measurements and simulations according to ISO 22955 and […]
Acoustic privacy and screens – What are the technical details?
How do you improve acoustic privacy in open offices? This might be the most important question for anyone designing or managing open office spaces as speech noise is the primary contributor to distractions for office workers [1]. The answer is that the right acoustic features must be in place, from the very base build of […]
