For building acoustics airborne sound insulation testing per ISO 16283-1 and for interrupted pink noise measurements with handheld analyzers, omnidirectional 360° radiation and high sound power from a dodecahedron are mandatory. However, if your daily work focuses on room acoustics reverberation time per DIN 18041 in classrooms or offices, using logarithmically swept sine chirps (ISO 18233 in Akulap) allows you to replace 15 kg of heavy gear with our 2.5 kg active speaker (Art. 6002).
100% Rental Credit Upon Later Purchase
If you decide to purchase the instrument after your measurement campaign, up to two weeks of rental fees are 100% credited toward the purchase price. All instruments are verified in our laboratory before shipment.
