Mer information
Beskrivning
The SP 91 is a hand-operated acoustic pulse source designed for measuring the reverberation time (RT60) of small and medium-sized rooms and open or echoey spaces of up to approximately 200 m² (600 m³). With peak sound levels of up to 125 dBC, the SP 91 delivers a strong, broadband impulse that is ideal for accurate acoustic decay analysis. It's simple, purely mechanical design ensures consistent and repeatable results, eliminating the need for batteries or external power. The SP 91 offers a sustainable and durable alternative to disposable sound sources, such as balloons, making it ideal for building acoustics measurements and educational demonstrations. Each set includes the acoustic pulse source SP 91, hearing protection and a lightweight carrying bag for easy transportation and storage.
