Acoustic Terms and definitions Sound Insulation : Definitions, Terms, Units and Measurements Sound Insulation is the ability of building elements or structures to reduce sound transmission To compare sound insulation properties you need to take into account the area of the dividing partition/wall, as well as the volume and sound absorption properties of the receiving room. [...]
Noise is used to create a 'sonic net' that blocks out bird of prey sounds Research was done at an active airfield in Virginia over eight week period Results show there's an 82 per cent reduction in birds in the treatment area Birds are generally considered hazards in the world of aviation as a [...]
Great to meet Dermot Bannon at the Portershed Galway today. We discussed the new building and the acoustics of this fabulous new innovation space in Galway City Centre. What a wonderful space and I think he was very impressed.
Its official, BS EN ISO 16283-2:2015 has been released. The standard specifically addresses — Field measurement of sound insulation in buildings and of building elements, Part 2: Impact sound insulation. Using an approved tapping machine, calibrated type 1 instrumentation and building acoustics software, impact sound insulation can be measured on separating floors between residential dwellings. https://www.youtube.com/watch?v=Wdz-wZQQlfQ If you [...]

Here is a short video on how traffic noise is measured and dissected. Modern instrumentation allow one to examine frequency content for each vehicle type which is essential for accurate prediction and the design of noise barriers (and their likely effectiveness). https://www.youtube.com/watch?v=qOzS2GJjDKg
A wonderful day to measure traffic noise in Ireland. Did you know that traffic noise is circa 3dB(A) higher when roads are wet. This is not considered in many Irish traffic noise predictions. Are you affected by Road Traffic Noise (RTN). NRA guidelines on traffic noise, CRTN, DMFRB and noise barrier design services.
People living under flight paths at Dublin Airport have revealed their daily nightmare as negotiations are planned on limiting the noise impact of a second runway. Aviation chiefs have offered to buy 40 homes, believed to be in the St Margaret's area 2-3km from the airport, ahead of the planned 320 million euro expansion in [...]
From buzzing phones to quivering console controllers, haptic feedback has become indispensable in modern computing, and developers are already wondering how it will be felt in systems of the future. Sending ultrasound waves through the back of the hand to deliver tactile sensations to the front might sound a little far-fetched, but by achieving just [...]
