Four sound test records in their covers, manufactured by xxx in
These records by architect and acoustician Hugh Vivian Taylor.
Hugh Vivian Taylor started practice as an architect in Victoria, Australia during 1923 and in acoustics in 1928.
The arrival of "talking pictures" in Australia in 1929 required acceptable acoustic conditions to ensure satisfactory reproduction of the sound. From 1930 to 1941 he acted as consultant for at least 434 theatres and public halls.
Acoustic equipment is used to measure the intensity of sound within an environment, for example outdoors or within a building.
The equipment consists of a microphone and sound level meter to pick up the sound, an analyser to determine the properties of the sound, for example, frequency and intensity, and an output meter to measure these properties. In some cases, sounds are produced using test records, for example in a building,
The key instrument is the sound level meter with its microphone. All the other instruments take their input from the sound level meter. These instruments include sound and vibration analysers and tape recorders.
In many cases, the acoustic equipment is used to test materials and environments using sound of a defniite frequency. The four test records, when played, produce pure tones at different frequencies. Each record has a different range of tones.
The tones might be used in testing acoustical properties of materials, the different parts of a room or the acoustical characteristics of an auditorium, such as reverberation times, reflections and echoes. The records could also be used for calibration purposes.
The four Victor 78 rev/min test records (containing tracks of single frequency sounds) recorder along with a Byer tape recorder were probably used by H. Vivian Taylor for reverberation testing.
