CESVACESVA has sound sources to measure insulation and reverberation time, as well as amplifiers and machines for measuring and assessing impact sound insulation.
Nowadays, good insulation means a comfortable home. The constant increase in urbanised noise has become a serious problem. This is why the efficiency of acoustic insulation needs to be improved constantly in order to achieve maximum comfort inside the home. The way to assess acoustic insulation is by measuring it (ISO 140), then rating it (ISO 717), with both airborne sound insulation (between rooms, facades and of building elements) and impact sound insulation. The reverberation time (RT) is a parameter that must also be evaluated, for optimum comfort in the home... |
