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?

Measurements at the Royal Festival Hall


The Acoustics Group undertook room acoustic measurements at the Royal Festival Hall for the London Philharmonic Orchestra. The assessment will be used to establish the quality of the
stage acoustics. Some of the Masters' students came along to the evening measurements to learn about low noise level testing

Measurements at Henry Wood Hall


The Acoustics Group undertook room acoustics measurements on 10th March 2009 for the London Philharmonic Orchestra at Henry Wood Hall, Trinity Church Square, London. The LPO use the space as a rehearsal room as do the LSO and RPO. TheA assessment will be used to change the natural acoustic of the hall.

Brighton Dome Measurements


On Saturday 7th March 2009 the Acoustics Group undertook architectural acoustic measurements at the Brigton Dome for the London Philharmonic Orchestra. We were impressed! The artifical reverberance system worked well, but it didn't need 2 hours to warm up! The LPO then put on a beautiful programme, which we measured (and enjoyed ) using 10 dose badges. This provided the finale to a very long day!

Glyndnebourne Orchestra Pit- Mind the Trap


The Acoustics Group were down at Glyldnebourne on Saturday 7th March to measure the acoustics of the orchestra pit. We now have design ideas to improve the sound for both the musicians and the audience! Well done Georgia and Christos for getting out of bed very early!
