Beskrivning
The SP 91 is a hand-operated acoustic pulse source designed for measuring reverberation time (RT60) in small and medium rooms and open or echoey spaces up to approximately 200 m² (600 m³). With peak sound levels up to 125 dB(C), SP 91 delivers a strong, broadband impulse suited to accurate acoustic decay analysis, while its purely mechanical construction provides consistent, repeatable performance without batteries or external power.
As a durable, sustainable alternative to disposable sound sources such as balloons, SP 91 supports building acoustics measurements and educational demonstrations. Each set includes the acoustic pulse source SP 91, hearing protection, and a lightweight carrying bag for convenient transportation and storage.

Features
Ready to use in field
Mechanical, battery-free operation
Hand-actuated impulse generation suits deployment in small and medium rooms and open or echoey spaces up to ≈200 m² (≈600 m³). Consistent, repeatable output supports RT60 measurements without external power.
Impulse RT60 made easy
Broadband, strong impulse
Peak levels >125 dB(C) at 1 m (semi-free field) provide a clear, broadband response for reliable acoustic decay analysis. Even spectral content supports frequency-dependent RT60 evaluation.
Robust and compact
Durable build, easy transport
Wood-based, textile, and metal elements with porous absorber filling support long service life. The SP 91 set includes hearing protection and a lightweight carrying bag; compact form factor (300×150×100 mm; ≈2.27 kg) facilitates movement between measurement locations.
Applications
Building and room acoustics
Rapid reverberation-time (RT60) assessments in small and medium rooms
The SP 91 acoustic pulse source enables rapid reverberation-time (RT60) assessments in small and medium rooms and in open or highly reflective spaces up to ≈200 m² (≈600 m³). A powerful broadband impulse—peaks up to 125 dB(C) at 1 m in semi-free field—yields clean decay curves and sufficient signal-to-noise for frequency-dependent analysis. Purely mechanical operation supports repeatable multi-position measurements without external power, facilitating on-site surveys and educational demonstrations.
