In many projects measurements are common to check and verify the acoustic performance, before, during or after construction. As a result of such measurements the design can be optimized and construction faults can be detected.

Sound isolation
The sound isolation between rooms and of a façade can be measured. We have to our disposal special techniques to measure very high sound insulations and to carry out measurements even under noisy conditions.

Room acoustic parameters
By using impulse techniques and the acoustic software DIRAC we are able to measure all room acoustic parameters to describe the acoustic quality of a space. Besides the reverberation time, a number of other room acoustical parameters to investigate and describe the acoustics of concert halls and theatres can be measured. Examples of such parameters are the sound strength, clarity and listeners envelopment.

Speech intelligibility (STI)
In cases where the intelligibility of speech is of high importance, like in offices and auditoria but also using public address systems and voice emergency systems in public buildings, we can measure the intelligibility by the STI method. Other quantities can also be measured like the STIPA and RASTI.

Sound level
To investigate the noise of the mechanical systems and to analyze the cause of noise, detailed sound level measurements can be done.
