Side tone and cell phones --

This is a bit more complicated than giving the user feedback of their  
own
voice.  Another aspect of this is how high the ambient noise level is  
during
a call.  The higher the noise level the harder it is to hear the  
person you
are talking to and it is natural to compensate by talking louder.

As far as the bank goes and their objections to use of cell phones I say
tough.  The solution to this is to not have twenty minute lines.  Any
business who does not have a solid monopoly who keeps me waiting that  
long
finds that I take my business elsewhere.

What this bank needs to do is cut the wait as much as possible and  
create
processes to make waits more convenient.  For example why not call  
people by
number and offer phone booth sized cubicles to lower noise levels  
while they
are waiting?

The banking industry is to put to put it mildly arrogant... and  
greedy.  A
few years ago I started transferring all my business to credit unions  
(and
encouraging other start-ups to do the same).  What has become Chase  
has now
lost about a dozen accounts.  I only have two left to transfer. These  
are
business and personal accounts.

I am considering switching from credit cards to debit for many of the
entities, to cut the banking industry out of all the tolls they are
collecting on the credit cards.  I have not needed credit in many years.
The only reason to use the cards is convenience.  And while on the  
issue of
credit cards I get lots of feedback from members of our organizations  
and I
strongly urge people to use credit unions rather than banks and to  
stay as
far away from American Express as possible.  The only thing Amex does  
well
is milk their customers.

Good business is based on equitable profit and in business to business  
deals
mutual profit.

One last swipe at the banking and insurance industries who are key  
players
in the outrageous property grab they like to call patent reform.  The
highlight of the banking industry's inventiveness is creating ever  
larger
and more outrageous fees.  And the insurance industry's claim to fame is
stiffing people out of their due.

Hi Dave:
Remember good old "side tone"?   Back in your Bell Lab days Dave,
remember when wired telephones were designed to leak a sample of  
signal from
the microphone back to the earphone to assure the user that he or she  
was
being heard at the other end.  If you spoke too loudly you heard  
yourself
and automatically then spoke more softly.
This acoustic feedback reduced the dynamic range of signals the phone  
system
had to handle, and people rarely shouted into their wired telephones.  
It was
win-win for all.

With cellular telephones the speaker and microphone tend to be close
together, so implementing side tone is more difficult than in a  
conventional
wired telephone. (The feedback could cause a loud
squeal.)  But, today we have wonderful signal processing in a small chip
area that could address this issue.  The underlying assumption is some
cellphone users shout thinking they will not otherwise be heard  
clearly. If
so, then, requiring acoustic feedback in cellphones would encourage  
them to
speak more softly -- as the sound of their own voice otherwise would  
be so
loud as to be uncomfortable. Might this allow us to instill a little
politeness into some cellphone users, without having to do so in an  
impolite
manner?

What do you think, Dave?

Paul , I completely agree.  On All Things Considered, December 15, 2004
(http://www.npr.org/templates/story/story.php?storyId=4229967)

on a program titled "What's behind the shouting on cell phones" I  
suggested
the same path to alleviate the problem.

Dave
