New acoustic standard for hospitals in Denmark This year a new acoustic standard for hospitals will be approved in Denmark. Up until now there has only been some rough guidelines (not mandatory). The acoustic demand will be on reverberation time. The value will be 0.6 sec. in e.g. patient rooms, examination rooms and corridors. There […]
5 tips for the hearing impaired
One of our editors, Morten Roar Berg, has recently been a speaker at an event for hearing impaired people. Here are his reflections after the event. Recently I had the pleasure of doing my first presentation for a crowd with either inborn hearing impairment or hearing damage. It really broadened my professional perspective. In my […]
Euronoise 2018 – A cochlea in the floor carpet caught my eye
Euronoise 2018 was a great acoustic event, and we at Acoustic Bulletin are proud to have covered 6 sessions on room acoustics in particular. This is the last post written by our development engineer, Heléne Sallenhag – she has covered the session 18:3 – Voice accommodations in room acoustics and noise. How much would you spend […]
Euronoise 2018 – Reduce Noise to Improve Life
This year Euronoise was held in lovely Crete (close to the Knossos Palace) from the 27th to 31st of May – and in the impressive surroundings more than 700 delegates from all over the world attended more than 50 structured sessions in total. Room acoustics were on the agenda every conference day and this article aims to […]
Free Field Conditions at Gentofte Hospital
Intervention study in an audiology department As part of the course ‘Architectural Acoustics’ at DTU – Technical University of Denmark, four students (Tobias Thydal, Vamsy Maddipati, Kat Herlo Benfelt Jensen and Christian Pedersen) chose to do an intervention study at the audiology department at Gentofte Hospital near Copenhagen in Denmark. The primary scope of the project […]
BNAM 2018 Reykjavik
Did you miss out on the Baltic-Nordic Acoustic Meeting (BNAM 2018 Reykjavik )? Here are the major take-aways from a healthcare acoustics perspective. Harpa Iceland has it! Impressive nature, impressive people – and the impressive Harpa Concert and Conference Centre. Harpa is one of Reykjavik‘s greatest and distinguished landmarks. It is a cultural and social […]
Room acoustic descriptors – RT, C50 and Strength/ Gain
Reverberation (RT) time still remains the primary indicator of room acoustic response and RT is also known to be the only demand/descriptor in building regulations for room acoustics in healthcare facilities, schools and day care centres and offices. However, previous work and research for many years has shown that RT alone can be insufficient to […]
The effect of scattering in rooms with acoustic ceilings
Rooms with acoustic ceilings Today we see a lot of public rooms with acoustic ceilings – and that is good! But in these rooms especially the reverberation time and speech clarity does not only depend on the absorption material in the room. Scattering plays an important role for the room acoustic design and therefor furniture […]
Input data – how do we predict room acoustics?
Calculation tools Recently a new acoustic calculation tool has been published. It is based on Air Flow Resistance (AFR) and calculates several room acoustic descriptors. This article aims to explain why calculations based on the Sabine equation are not always the whole truth. Background – Sabine and ISO 3382-1/2 A long tradition of research shows […]
Acoustics to support recovery in Satakunta Hospital
A hospital is a challenging environment in terms of acoustics and to support recovery. There is a constant flow of people moving around the spaces. The rooms themselves feature no shortage of hard surfaces, and a range of different equipment makes the spaces even noisier. The acoustics must also be capable of meeting high hygiene […]
