Re: Equal loudness contour filter

You also might want to try the Loudness Toolbox for MATLABÂthat
Genesis Acoustics announced on the auditory list last March. ÂIt
includes both the ISO (Zwicker) and ANSI (Moore and Glasberg)
standards for stationary and non-stationary sounds.


I have also used the the Adobe Audition "Group Waveform Normalize"
with some success.

Hope this helps.

> ÂÂÂÂÂÂÂÂÂÂÂÂÂ Happy New Year to all. I am designing a test in which there are pure-tones stringed together with each other in the range of 100-500 Hz (15 logarithmic steps). The reference tone is always 100 Hz and the variable tone is in the specified range. My main intention is to assess the perception of the pattern/rhythm of these sequences based on just the pitch/frequency cues but the difficulty that i have is there are additional loudness cues involved as i am dealing with a range of different frequencies. As i am designing this test for children it will be very difficult for me to do a loudness balance task to equalize loudness. I was wondering if there is a possibility that i can use a equal loudness contour based filter to filter the tones as to equalize the loudness. It will be a great help if i anyone can share any information or if can get such a filter.
