Larson Davis 824 Sound Level Meter

Larson Davis 824 Sound Level Meter

Larson Davis 824 sound level meter, works perfectly and was last laboratory calibrated in 2016. It has bene under the caring ownership of acoustical engineers for its entire life thus far! The instrument is feature-loaded with both environmental acoustics and architectural acoustics firmware.

• Interval logging of overall sound pressure level (Leq, Lmin/Lmax, Ln percentiles)
• Interval logging of 1/3 octave band sound pressure level spectra (Leq, Lmin/Lmax, and Ln percentiles)
• Overall reverberation time measurements (e.g., RT60)
• Reverberation time measurements based on individual 1/1 and 1/3 octave bands

All instrumentation meets ANSI/IEC Type 1 standards.
