A scalable sound insulation measurement system that grows with you

Lightweight, DS3 omnidirectional Loudspeaker 
Measuring airborne, façade, and impact sound insulation follows a standardized procedure involving several measurement steps. Depending on which sound insulation test you are performing, you will need a sound level meter, a loudspeaker, and a tapping machine. To better meet our customers' needs, NTi Audio has developed the EXEL Building Acoustic Kit, a collection of measurement tools optimized for low weight, simple operation, and excellent performance. All at an attractive price.

The XL2 Sound Level Meter quickly and easily takes 1/3rd-octave level and reverberation time measurements required for the rating of insulation against airborne, impact, and façade sound transmission.
