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 […]
room acoustics
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 […]
Conference on inclusion and hearing impaired children
So, the iCARE research project (improving Children’s Auditory Rehabilitation) is coming to an end, and I had the privilege to participate in one of the last major milestones, recently executed (November 20-21 in Leuven, Belgium) – namely the iCARE conference. Professor Dr Astrid van Wieringen has been project managing all of us during these years, […]
Danish study: 97% of hospital staff are sometimes disturbed by noise
Danish study on healthcare facilities. Presentation day Today I had the pleasure of attending a presentation day at DTU (Technical University of Denmark) arranged by the Electro Department under the title: Acoustic Technology & Centre for Acoustic-Mechanical Micro Systems. The speakers were mainly PhD students and Postdocs and the topics varied from ‘Loudspeaker Array Auralisations […]
The Problem With Acoustic Simulations
Predicting sound absorption is in general troublesome. We have too many definitions; e.g. normal incidence, random incidence, field incidence, angle-dependent absorption coefficient, local-reaction or extended reaction absorption coefficient, etc. Another problem is that there are various standardised methods, but none of them can give an absolute truth. Cheol-Ho Jeong, Associate Professor at DTU, was one […]
Interview with Acoustic Bulletin editor; Yvette Tietema
We’d like you to meet the fantastic editors here at Acoustic Bulletin. Most of them have the same job title, ‘Concept Developer’, but what does that mean? And who’s really behind the title? Because even though they share the same title, are very knowledgeable in room acoustics AND super-friendly and helpful, each of them has their […]
Sensing the space – New podcast episode
In this special edition of the A Sound Effect on People podcast, we join Lauren Kruger and Dr Annemarie Lombard in South Africa and delve into the effect of our senses and so-called sensory intelligence in our daily life. Click and listen This episode gives an insight into how the sensory stimuli affect the way we act within our […]
Better performance during the teacher training sessions – highlights need for good school acoustics!
Case study: How acoustics dramatically improved the teaching facilities at training centre for teachers CESIRE, Barcelona, Spain Above: dBplus Acoustics explaining acoustic improvements One good thing leading to another The idea behind the collaboration between CESIRE, dBplus Acoustics and Ecophon came about after Ecophon hosted a knowledge seminar in Barcelona which shared a local case study […]
Sound schools: the importance of good acoustics
When we speak, we push air from our lungs, which continues up through the neck via the vocal chords, which in turn vibrate and create sound. The sound continues on via the nasal cavity and oral cavity, creating sound waves that are released into the room. These sound waves are received by someone’s ears via […]
Sound and school design from three architects’ point-of-view
In this post, we have collated three architects’ views on the role of sound in designing school buildings. The listening architect Architects focus on sight, as this has been quoted by giants such as Aristotle, Vitruvius, Palladio and Corbusier as “the noblest of all arts”. In other words, sight has been perceived by many as the […]
