Today almost all room acoustic calculations are based on the Sabine formula. Even though it is known that you often get different values when you compare calculations with actual measurements in a room. Therefore, Ecophon has developed a calculator in which the intention is to have more accurate acoustic values before measurements. The Ecophon Acoustic Calculator is […]
There’s an important difference between music and speech. The brain is capable of “filling in” a fair amount of missing information in music. There’s a high degree of predictability. Generally while hearing music, if you didn’t get the bass line or some part of the song which you are keen on listening in the first […]
The theme for the upcoming World Hearing Day 2019 is “Check Your Hearing”. On the 3rd March the WHO (World Health Organisation) will draw attention to the importance of early identification and intervention for hearing loss. Many people live with unidentified hearing loss, often failing to realise that they are missing out on certain sounds […]
An evidence-based study to raise noise pollution awareness was presented last month at INTER-NOISE 2018 in Chicago by Gregory Scott, Founder of SoundPrint. This is, according to the Abstract: The first large-scale study conducted on sound levels, using the novel SoundPrint smartphone app, of more than 2250 venues in New York City shows that the average […]
We asked Tim to give us a summary insight into his recent Thesis which he has completed as part of a collaborative Lund University study report with Ecophon. Tim is a qualified architect (Arkitekt MSA), has just recently completed his Master Thesis at Lund and is now a consultant helping other architects understand and include […]

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 […]
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 […]
