Acoustics in green buildings, by Hassan Al-Ramadani Over the last twenty years, there has been a remarkable surge in the construction industry’s adoption of green buildings. This has been due to public awareness of adopting sustainability and sustainable practices. Additionally, several studies have proposed that occupants of green buildings have a higher level of productivity […]

Improving acoustic comfort in swimming pools
Insights from Jeroen Vugts and Pien Schravesande at EAS 2024 Swimming pools, with their lively and dynamic environments, present unique acoustic challenges that are often overlooked. At the recent Ecophon Acoustic Seminar (EAS) in the Netherlands, ir. Jeroen Vugts and Pien Schravesande of LBP Sight presented an insightful discussion on the critical role of acoustics […]
Tackling acoustic challenges in open-plan offices
Increase in open-plan solutions Open-plan offices have gradually become a preferred model for companies to use, mainly to encourage spontaneous interactions between coworkers, but also because of the aesthetics around a big open room. Further, there is an economic benefit of having as many workstations as possible in fewer square meters. However, these benefits often […]
Renewed Room Acoustic standard, SS 25268:2023
Introduced in April 2023 the renewed room acoustic standard SS 25268:2023 [1] for the Swedish market is now less than a year old. The background and purpose of the standard is, among other things, to supplement the Swedish National Board of Housing, Building and Planning’s building regulations and other governing documents and to facilitate planning […]
People’s preferences of sound
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 […]
Robotic surgery – precise but noisy
Operating rooms for robotic surgery require sound absorption for lowered sound levels and improved speech intelligibility. Introduction Operating rooms (OR) in hospitals are supposed to be quiet, controlled spaces that allow doctors and nurses to focus on performing complex surgeries. Unfortunately, the reality is often very different. Noise from medical equipment, combined with poor room […]
Active room acoustics through electroacoustics: Amadeus Acoustics
One of the most common questions that you will hear in active room acoustics is: “what would be the best reverberation time for my room and how do I get there?”. The counterquestion needs to be: “what do you want to do in your room?”. And therein lies one of the common problems for room […]
Case study: Psychological and pedagogical counselling centre no. 19 in Warsaw
Psychological and pedagogical counselling centre no. 19 (PPP19) is a place that assists children and their parents living in the district Ursynów in Warsaw, including children from nearby schools and kindergartens. The centre helps in reaching the right diagnosis about e.g. language, memory and intellectual abilities and supports children’s mental development. The number of patients […]
Sound environment in the Intensive Care Unit
Noise levels – how it is experienced by staff We have building regulations for room acoustics in hospitals in Intensive Care Units (ICU). But are they enough to create a good environment for both staff and patients? Recently a new study from Copenhagen hospitals was finalized so let’s take a look at some of the […]
Modular operating rooms provide good acoustics for surgeons
Lego construction for operating rooms Modular operating rooms are being seen more and more on the market. It takes less time to get it up and running compared to a traditionally built hospital. It´s cost-effective, time-saving, and can be taken down and moved when it´s not needed anymore. However, it can negatively affect acoustics due […]
