Dynamic range compression modification of a digital telephone switch for individual hearing characteristics
First Claim
1. What I claim as my invention is the application of a specific filter (defined above) on a telephone soft switch to allow to allow auditory signals modified by dynamic range compression to go to specific customers. The specific use of the filter for the purpose of modifying phone reception for minimal high frequency hearing loss is the sole claim in this application.

Abstract
A phone reception system that provides differential volume at different frequencies is made available on demand by application of a multiband dynamic range compression filter to enhance the normally audible spectrum of a signal. Audio components that lie above a person'"'"'s sensitive hearing regions are amplified so that they can hear and understand them. The modifications are available on demand through a message from any remote customer premises equipment or business phone to the softswitch.
