FCC talking about relaxing cell phone rules

I don't blame the phones either - they just provide a con-
venient excuse for the inconsiderate in our midst to show
their true nature.

Actually, the phones do share some of the blame. There is little to
no sidetone in cell phones (that I've used). The first time I used a
cell phone I made a call to my aunt to test it out. A few minutes
into the conversation I realized I was shouting into the thing just
like all the other people whose cell conversations I despise. I
wasn't trying to be inconsiderate - but the cues provided by the
earpiece (that I'm being herad) did not exist. With more sidetone in
the earpiece, people naturally talk more quietly.

Now when I use the phone I make extra effort to talk quietly, but it
is not natural the way it is on a regular phone.

My question is "what is the
difference"? My radio was simply people talking - and we
were surrounded by talking people!

One difference is the tone quality. A radio speaker typically emits
only treble, and it =sounds= different from a regular conversation.
The experiment would be interesting repeated through a hi-fi.

I suspect that this is part of the issue with cell phone use while
driving. The sound is tinny, comes through one ear, is often a
tenuous connection, and is full duplex. This requires more brainpower
to process - not enough more that we'd notice without something (like
accident rates) against which to measure it, but more nonetheless. A
two way radio in the car (like an aviation set) would be half duplex,
higher quality, and come in both ears. (Half duplex is important
because it means that you don't have to listen while you're talking.)
I have found it's much easier.

Maybe the final solution is to pass a law that all cell
phones must be in the form of a helmet - from which all
sounds made or heard by the user must be inaudible to others
at any distance greater than 12 inches.

The cone of silence goes mainstream!

Freedom. It seemed like a good idea at the time.
for Email, make the obvious change in the address.

I agree that sidetone is a valuable aid to making the use
of a communications device seem more natural and intuitive.
Perhaps this should be a parameter that is user-adjustable
(at the risk of causing feedback if set too high).

I also agree that the fidelity and perceived audio quality
of small speakers leaves much to be desired. Perhaps such
sound quality is irritating to some people - but then some
are hypersensitive in general. Since I'm a daily user of
such devices, I tend not to notice. I have a "hands free" adapter in my
work vehicle, and agree that using it provides
a remarkable improvement in sound quality. However, I tend
to use the "hands free" feature only when stopped. If the
phone rings while I'm on the road I will invariably pick
up the handset.

I do think that us pilots are more able to use a cell phone
while driving than the average joe. This is probably because
we are accustomed to multitasking and prioritizing our
sensory inputs. That would make an interesting subject for
a study. As for the safety aspect, I am careful to pull
off the road before dialing. Answering or continuing a
conversation already underway requires considerably less
attention.
As for the helmet idea - I'm being facetious, of course!

I don't know about you, but the traffic separation I consider acceptable in
an airplane is a lot larger than that in a car. Because of that, going
"instrument" in the car to dial the phone is scary .

Duplex means the sound travels back and forth; half duplex means
push-to-talk (at which moment the other party is silenced)?

Interesting analysis, thank you. It is certainly true for me that cell
phone conversations, and cell phone users, are particularly annoying.

I have noticed however that the most ubiqutous users--the students at
the state university which is my downtown--are much better than adults
on the streets of say New York. Perhaps because they have grown up
with the thang, so they know not to shout? Certainly I have never
heard a student say, as I heard a presumably high-paid businessman
boast as we were settling into a jet liner at Washington National
Airport, "Guess where I am?"
