Low frequency absorption test

On Friday 27th March the reverberation chmaber of the acoustics lab was used to establish the effectiveness of porous absorber in bags to act as a low frequency absorber. Many builders bags were filled to establish if 63 Hz reverberation time could be reduced. Thanks to all who helped shift the bags!

Acoustic Screen Under Testing

Studnets of the Royal Academy of Music tested the acoustic screen in the orchestra pit on 26th March 2009. We had timpani, flute and trumpet players perform and took 3 simultaneous measurement positions. From initial results an acoustic trick seems to work!

Students at the Royal Academy of Music

The MasteArs students in Environmental and Architectural Acoustics spent the morning of 26th March 2009 at the Royal Academy of Music. We needed many hands to measure the effect the acoustic screens in the orchestra pit from the conductor and audience positions. They were also shown the sound absorbing mirrors and the newly installed noise alert system. A special thanks to Bob for taking the equipment to Regent's Park for the tests.

Screen tested by Trumpet Player

Jayne Sutton of Capita came to the Acoustics Lab to play her trumpet in the anechoic chamber to test the effectiveness of the new acoustic screen. Jayne was trained at the Royal College of Music and played beautifully. Much apprepreciated. Thanks Jayne!

Masters Student at IoA London Branch

Gil van Buuren presented his Masters' dissertation on 18th March 2009 to the Institute of Acoustics London Branch. The thesis is entitled, "A parametric study of low frequency sound in listening rooms using a wave based numerical model". Although mathematical it was warmly received by a knowledgeable audience at the meeting held at Capita Symonds, Holborn. Next time less equations Gil!

New Acoustic Screen for Musicians

A new design for a small acoustic screen has been designed for musicians. The screen is designed to be used in orchestra pits for the Royal Academy of Music and the London Philharmonic Orchestra. Lets just hope it works!

Royal Academy of Music has 1st sound absorbing mirrors

The first effective sound absorbing mirrors were installed at the Royal Academy of Music by the Acoustics Group on 12th March 2009. The Noise Reduction Coefficient is 0.85. The question is how long will they last the student abuse?
