The Impact of Ceiling Profiles on Room Acoustics
Introduction The project aims to explore an underutilized aspect of acoustic optimization: the geometric design of ceilings profiles. While material-based solutions have been extensively studied and implemented, ceiling geometry offers a largely untapped opportunity. Research has consistently shown that ceilings significantly influence room acoustics. However, they are often treated as static, planar elements designed primarily […]
Salvation for civilization – could better listening be part of the solution….
“Listen to understand. Audioeducation for schools” A new book for teachers “Listen to understand. Audioeducation for schools” has been written to support teachers to create better conditions for deeper learning. We are living in a society which has increasing difficulty with attentive listening. Due to this, we talk over each other and argue instead of […]
Inter-Noise 2024: Healthcare Acoustics
It was with great pleasure we visited this years Inter-Noise in beautiful Nantes in France. Nantes is especially know for being the birthplace of Jules Verne, master of adventure who was also a poet and one of France’s most prolific authors of all time, with a specific interest in science. Some 1800 acousticians and researchers […]
After a full 50 years, Slovakia has a new acoustic standard!
Slovakia has a new STN 73 0527 acoustic standard that can finally improve conditions in schools! The new updated STN 73 0527 acoustic standard deals with room acoustics. In schools, universities, and spaces used for cultural, sports, social and public purposes. It aims at ensuring better quality and healthier acoustic conditions. New acoustic standard highlights […]
BNAM 2024: A step forward in acoustic innovation
Baltic-Nordic Acoustic Meeting (BNAM) 2024 is leading the way in acoustic innovation in the Nordic countries. This year, BNAM has been exploring new ways to distinguish itself among major acoustic conferences like Internoise and Forum Acusticum. One of the key strategies has been to offer not just ordinary presentations but also hands-on workshops with software […]
Baltic-Nordic Acoustic Meeting 2024
On May 22-24, some 175 delegates from 18 countries gathered together in the beautiful venue at the Finnish-Swedish Cultural Center Hanaholmen. Located at the scenic seafront between Helsinki and Espoo in Finland. Three days of conference targeted even more than before to the people practising acoustics every day. This meant that one of the Baltic-Nordic […]
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 […]
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 […]
A major survey in France : Noise in Bars & Restaurants
At EIAS 2023 a poster session was presented and lots of great studies were shared. Studies from Education, Healthcare and Office segments were covered at the same time as studies about sound environments in restaurants and bars. A poster including a survey from France revealed that restaurant owners risk lower income because of noise. The […]
