OPN 1 or Evoke 440?


That’s what I’d thought. And this is probably what is being done just based on Widex’s marketting. Initially they were heavily marketting their increased high end, and lately I’ve noticed a increase in focus on their low end. Suggests a certain reaction to what other companies are doing.

Next question is, do these two strategies make a perceptually useful difference for musicians?


From an interview with Marshall Chasin

"Academy: What about loudness and dynamic range in speech and music? Cold running speech typically has a 30 dB dynamic range, whereas music can easily have a 100 dB dynamic range.

Chasin: Well again, music is much more dynamic than speech. The loudest component of shouted speech is perhaps 80 to 85 decibels, when vocalizing the vowel /a/. Higher frequency consonants almost never exceed 60 decibels. In contrast, very quiet music often exceeds 80 to 85 decibels and loud music might approach 110 to 115 decibels (dBA) and perhaps some Wagner pieces may be even louder! Even though speech is very complicated, it is well defined. This is in contrast to music that is quite variable with regard to loudness and spectral components."


Now it seems to me that music coming into an aid at 114 dB that has a mic input threshold of 95-96 dB is going to be far more prone to distortion than one designed to cover the 115 dB. Amiwrong?


Another good article.



That was the problem with the 96dB range, input compression/clipping.

The higher bit systems don’t top out so easily.
