Subject: Devices for recording and impulse response measurements (UNCLASSIFIED) From: "Scharine, Angelique (Civ,ARL/HRED)" <AScharine@xxxxxxxx> Date: Thu, 25 Oct 2007 11:38:49 -0400 List-Archive:<http://lists.mcgill.ca/scripts/wa.exe?LIST=AUDITORY>Classification: UNCLASSIFIED Caveats: NONE We are considering the purchase of a portable recording system that can also be used to record transient sounds and to record impulse responses (using an MLS signal to elicit the response). Our previous system was unsatisfactory due to poor human factors of the software interface. This device needs to be portable enough to be used for outdoor measurements and recordings. It needs to allow for stereo input (recording through a KEMAR manikin). It should be able to handle very low frequencies (ideally down to 1 Hz). It needs to be able to record very loud sounds like gunfire - at least up to 140 dB SPL. Data analysis tools (basic ones like FFTs and sound pressure level measurement) should be available in the same program that does the recordings so that real-time information can be accessed. If you have, or know of a system that is easy to use and has worked well for you, please share it with us! Angelique Anyone can do any amount of work, provided it isn't the work he is supposed to be doing at that moment. -Robert Benchley Angelique Scharine PhD Army Research Lab - HRED AMSRD-ARL-HR-SD APG, MD 21005-5425 (410) 278-5957 (landline) 298-5957 (dsn) (410) 278-3587 (fax) Classification: UNCLASSIFIED Caveats: NONE
