AL1 Acoustilyzer

AL1 Acoustilyzer

The Acoustilyzer is a handheld sound level meter and acoustic analyzer for measuring and monitoring of sound pressure level at concerts, room acoustics and speech intelligibility STI-PA. The practical blend of electrical and acoustical functions, combined with computer connectivity, positions AL1 to be an indispensable tool for every sound/system contractor, installer and multi-media specialist. The sound level meter meets the standards DIN 15905-5 and SLV 2007.

The Acoustilyzer AL1 is available as a palm-sized portable acoustical analyzer or as firmware for Minilyzer owners.

Owners of the Minilyzer ML1 and Acoustilyzer AL1 firmware may switch between these two versions using the MiniLINK software.

The optional STI-PA analyzer software allows durable and reliable speech intelligibility measurement within 15 seconds. Besides the single value STI or CIS test result, a detailed view of modulation indices and individual band level results is provided. The STI-PA analyzer includes amplitude weighting in accordance with the 2003 IEC 60268-16 standards release.
