MEASUREMENT, ANALYSIS AND PREDICTION OF ROOM ACOUSTIC PERFORMANCE – ELECTROACOUSTIC MEASUREMENTS
Every enclosed space has certain acoustic parameters crucial to determine if it is suitable for a specific usage (e.g. music production, speech, etc.). In addition, these acoustic features frequently dictate the type and the specifications of a potential PA installation in this space.
In ALPHA Acoustiki, using state-of-the-art acoustic software and years of experience in the field, we can calculate and predict these acoustic characteristics of the room before it is even built.
However, using specialized equipment to perform on-site acoustic measurements, we can evaluate the room response in more detail. This is practically done by measuring the impulse response of the space at specific source/receiver positions using an omnidirectional sound source (dodecahedron speaker). Sine sweeps (or “Swept-sines) used as excitation signals provide a way to measure linear impulse response.
