Age-related hearing loss and acoustics

Age-related hearing loss affect almost all of us as we age. Good acoustics can promote not just hearing but also the ability to function and wellbeing. A calm acoustic environment benefits all of us, whatever level of hearing we have, but it is particularly important for those with hearing impairments. The most common cause of […]

Is it really possible to predict the room acoustic values in a non-diffuse room?

We made acoustic measurements as part of a remodelling of our training area at our head offices during the different phases of the acoustic treatment in the refurbishment. This is outlined in a previous Acoustic Bulletin post which highlighted the need for wall absorbers to remove the flutter echos, thus reducing the reverberation time and […]

Reverberation room vs Anechoic Chamber

Here is a short film where our editor Juan Negreira demonstrates some aspects around the acoustic free field, and the broad range of acoustic dynamics which can be found between two acoustic opposites. This is a chance to experience and share difference between being inside a room coated with highly absorptive material versus in a […]

Soundproofist – a practical approach to raising awareness about sound around us.

It was great to meet up with Cary Norsworthy at Internoise2019 in Madrid a few weeks ago. Her passion about the sound environment is driven from her own experiences and her curiosity to learn more about noise, acoustics and soundproofing – and share this with others. She not only is doing a great job raising […]

How about raising awareness about the need to check our hearing!

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 […]

School acoustic research overview says minimise sound levels whilst maximising speech intelligibility

Professor Emeritus Bridget Shield recently presented a comprehensive school acoustic research overview at the Transitions18 education research symposium in Copenhagen. Bridget’s overview highlighted that the importance of acoustics in schools has been know about for a long time although the research has only really accelerated over the last 50+ years. BS looked at the typical […]

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 […]
