To test buildings acoustic insulation, it’s necessary to use sound sources that meet the demands of specific technical ISO standards.


Delta Ohm has developed a system for the measurement of passive acoustic performances of buildings that integrates the most advanced features required for this type of equipment.
The need for high noise excitation levels, necessary to deal with increasing insulation values of modern buildings, has been made co-exist with portability and versatility among the best on the market today.
HD 2050 is a sound source composed of 12 speakers arranged in a dodecahedral chassis, capable of radiating high power sound energy in all directions with a directionality in accordance with ISO3382.
The sound source can be integrated with the digital amplification system HD 2050.20, which offers high power as well as providing an equalizer that adapts the system’s response to any more specific measurement needs.
