Normalizing phone volume based on passcode volume and historical ROLR values

Disclosed is a system for normalizing the phone volume of members on a conference call.

Currently in a teleconference, each person manually controls the volume of their phone on a conference call. Everyone calls into a central location, gives the passcode, and begins speaking. When a soft spoken person starts to speak, many listeners adjust the volume on their phone to be louder. When that person completes a sentence, another user calling into the same call begins to speak and their voice may be loud enough to cause physical pain because their phone was set to a maximum volume because they to were trying to hear and their speaking/listening volumes are identical.

The drawbacks to this manual solution are obvious.

For the truly hearing impaired listeners, there are standard solutions regulated by the FCC to assist them with hearing on a phone. [1]

However, not all hearing impaired individuals have this equipment, nor realize they need it. Some people are just loud or soft spoken and they don't realize this. The disclosed describes two techniques to help balance the volume of multiple incoming calls on a single conference call for those of use without hearing problems, who would like to bring the hearing volume into some sort of reasonable state, generally between 12 dB and 18 dB. [2]

The idea is to 'normalize' the volume of all of the calls at the central phone center when calling into conference calls. Today, the FCC requires the use of volume control on public phones, however, it does not require that a separate speaking and listening volume be provided.

The Receive Objective Loudness rating (ROLR) value is monitored and used to adjust the broadcast volume of a given phone. This adjustment is made for each in-coming volume for any participant to a conference call.

The first technique to adjust the volume occurs before a user even begins speaking. The conference system listens to the first 6 digits of an incoming passcode, and creates a common 'normal' value to broadcast to all of the participants on the call. This solves the problem where a user keeps their pho...
