In many projects measurements are a common way to check and verify the performance before, during or after construction. As a result of such measurements the design can be optimized and construction faults can be detected. Level Acoustics & Vibration has the facilities and knowledge to perform various acoustical and vibration measurements in the field, to analyse results and determine relationships. Below some of the measurements that we can perform are listed.
Measurements on location
Sound level
To investigate the noise caused by mechanical systems or other noise source and to analyze the cause of noise, detailed sound level measurements can be done.
Sound insulation
The sound insulation between rooms and of a façade can be measured. We have special techniques to our disposal 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 the room acoustic parameters to describe the acoustic quality of a space. Besides reverberation time, a number of other room acoustical parameters can be measured, for example to investigate and describe the acoustics of concert halls and theatres. Examples of such parameters are the sound strength (G), clarity (C80) and listeners envelopment (LF).
Speech intelligibility (STI)
In cases where the intelligibility of speech is of high importance, like in offices and auditoria, but also in spaces where public address systems and voice emergency systems are used, we can measure the intelligibility of speech by the STI method. Other quantities can also be measured like the STIPA and RASTI.
Sound absorption
Using surface scanning techniques with the Sonocat we can measure the sound absorption of materials in the field.
Vibration
We have several high-sensitive accelerometers at our disposal to measure vibrations of floors, machinery or larger objects like ships.
