Acoustic treatment for a piano practice room: Galleria Music School

The customer is Galleria Music School, in Sin Ming Plaza Tower 1, Singapore. There is an upright piano in each teaching studio, backed up against a wall. The studios are small, carpeted, but with highly acoustically reflective walls of glass and plastered brick. As a result the sound level in them is intolerably high, and the pianos are tonally bright and ‘jangly’. In two studios the problem has been addressed by putting two UNISON SAP-75 panels in a six-inch gap between the rear of the piano and the wall. The panels are in portrait orientation and sit on the carpeted floor; no floor stands are used. The panels have cut the loudness of the pianos. The tonal character of the pianos has also been greatly improved – they are much more tonally balanced.

Acoustic treatment for a music practice room: Yamaha AvantGrand N3 in a bedroom

The customer Mr K is an avid amateur pianist. He owns two grand pianos (Sauter Delta, Shigeru Kawai SK-6), and a Yamaha AvantGrand N3 hybrid piano. The Sauter and Shigeru Kawai grand pianos are located in the living room, whereas the Yamaha AvantGrand is located in a small bedroom.

The AvantGrand N3 is capable of playing as loud as a real piano. Although the loudness can be adjusted via the AvantGrand’s volume control the room imparts a ‘boxy’ colouration to the lower half of the keyboard, and a rather harsh ‘glare’ to the upper half of the keyboard. Bass articulation is also indistinct because of strong room modes. Mr K uses four UNISON SAP-75 panels on floor stands and six UNISON D-C diffusors on the ceiling to tame the room colouration. The ceiling diffusors also eliminated the intense slap-back echo off the ceiling, by dissipating the reflections rather than absorbing the sound.

What I’ve been busy with

It’s been a long time since my last post in June last year! I’ve been so busy that I even forgot to post a couple of drafts that I had in the works, including pictures and impressions of Lang Lang’s recital in Singapore last November.

What kept me busy? Working my day job and in my spare time helping out a small business named AudioRev. Their website went live yesterday.
