Subject: SPL meters From: Sheila Williams <williams(at)psyvax.PSY.UTEXAS.EDU> Date: Wed, 29 Apr 1998 12:37:47 -0600Thanks for the responses so far. perhaps I should have said that we are doing experimental work on speech perception - (usually, or possibly always) over head-phones so we need to calibrate our experimental set-up. Free-field maesurements are not usually required, but coupling to head-phones of various shapes and sizes is essential We probably also need one with more than one weighting option depending on how speech-like our (synthetic) signals are. thanks for the replies so far - I will collate and post all responses and any other apparently useful sources I find in my web trawls.
