Accessories for Acoustilyzer AL1
MiniSPL, Class 2 Measurement Microphone
The MiniSPL is the ideal accessory for the Acoustilyzer AL1 and Minilyzer ML1. Its self-powered design, the individual factory adjustment and the auto power-off control combine to make the MiniSPL an accurate, easy to handle yet affordable measurement microphone.
The servo-loop output stage design supports long cable connections between the analyzer and the microphone - up to several hundred meters. MiniSPL is also recommended and easy to use in conjunction with PC based measurement systems with high quality audio cards.

STIPA Speech Intelligibility Option
The STIPA analyzer option allows durable and reliable speech intelligibility measurement within 15 seconds (typical). Besides the single value STI or CIS test result, a detailed view of modulation indices and individual band level results is provided. The STIPA analyzer includes amplitude weighting in accordance with the IEC 60268-16:2003 standards release.
Acquired measurements may be referenced to previously-established background noise level spectras with automatic recalculation of the STI values.
The STIPA Option requires the ML1-AL1 Crossgrade pre-installed in the Minilyzer.
