New measurement system will 'aid room acoustics understanding'

摘要

Marshall Day Acoustics has released a new measurement system that it says promises to provide a dramatic step forward in being able to understand the acoustics of rooms. The IRIS system comprises a tetrahedral microphone that can resolve the sound field into different directions, and software that can analyse the signals from the four microphones and present the information in "a simple yet elegant way that aids one's understanding of the behaviour of the sound field". The system has been under development for nearly three years but it has its origins in the efforts by many researchers over the last 60 years to understand the factors that affect people's appreciation of speech and music performed in concert halls, opera houses, lecture theatres and all the wide variety of spaces that are used for performance and communication.
