Subject: Re: Annoyance of cell phone use in public spaces From: Peter Lennox <peter(at)LENNOX01.FREESERVE.CO.UK> Date: Tue, 7 Aug 2001 22:36:19 +0100Taking point a) first, - it seems to me that this is explicable in terms of 'territorial instincts" (however you might define them), and "status transactions". Normally, people who 'enter our space' engage with us in one of a variety of ways, but all according to implicit 'rules' about territory. A 'low status' invader will be overly conciliatory, a high status invader will deliberately ignore our territorial rights in favour of his(/her) own; he/she will move swiftly and unambigouously to consolidate 'ownership' of the territory with minimum bloodshed, so to speak. The most complex and time consuming transactions occur where all participants are of a similar status (most obviously so where the participants are young males!). The point of this is that mobile phone users often unwittingly trample all over this 'territorial ettiquette', because they are actually deeply involved in a territory not physically present to others in the same physical 'place'. The effect is one of being 'actively ignored', which is quite different to the 'passive ignoring' which occurs in crowded public places. (A similar effect can be had when trying to conduct a conversation with a receptionist [or whatever] who is simultaneously gazing at a computer screen). One effect of these situations is that the person speaking on the mobile will be speaking in an active and outgoing way (whilst ignoring those physically present) and will therefore seem to be talking louder than they actually are. Combine this with the situation where the phone user will be attempting to understand a 'place' which is impoverished in signal terms and in information terms, as it is in competition with the characteristics of the physical location of the speaker (which may well be downright noisy), and the impression is of a poor signal-to-noise ratio, so of course they may tend to shout. A similar effect can be observed when a sound engineer works with a group of vocalists in a band: the engineer can manipulate the quieter members into singing louder by lowering their 'foldback', and the same principle can work (in reverse, as it were) with the louder members. I've a hunch that delaying the speaker's own voice slightly before feeding it back to them through the earpiece might have the effect of it being more perceptible and therefore the phone user would tend to speak quieter (bit like in a museum). Incidentally, I've noticed on several trips to Finland that people there speak very quietly on the mobile! - are Nokia phones better? is Finland generally quieter? or are Finns more self-concious? - to be fair, I have no experience with 2nd-hand car dealers in Finland, so this isn't a conclusive observation. regards, ppl ----- Original Message ----- From: "Hannes Muesch" <hmuesch(at)HOTMAIL.COM> To: <AUDITORY(at)LISTS.MCGILL.CA> Sent: 06 August 2001 22:32 Subject: Annoyance of cell phone use in public spaces > Dear List > > I am afraid I am not the only one who is at times annoyed by having to > overhear mobile phone users ranting in public spaces.
