Loudmouth mobile phone users on trains and buses in Western Australia will be targeted in a new campaign to tackle the growing annoyance, according to the PerthNow website.

Blaring portable music players will also attract attention from transit officers, who will ask passengers to quieten down.

The Public Transport Authority will roll out a series of posters aimed at tackling what is fast becoming public enemy No.1 on public transport.

Nuisance passengers who refuse to lower the decibels risk being kicked off public transport.

"We expect this will be self-regulating and will not lead to serious confrontation because transit officers are trained in mediation and conflict resolution," Public Transport Authority spokesman David Hynes said.

"They are entitled to ask people to leave the train if they continue with any offences, but we hope this issue will not come to that.

"Once the posters go up, there will be fair amount of peer pressure applied because there will be something there in black and white for everyone to see.

"This is all about showing manners and respect for other people."

Transport Minister Simon O'Brien said he fully supported the campaign.

"I encourage people to show courtesy when using our public transport system," he said.

This week, The Sunday Times conducted a commuter survey, which clearly identified loud mobile phone chat and noisy portable music players as the top two annoyances.

Ear-piercing polyphonic ringtones were No.3 in the straw poll of 50 people at Perth train station and bus stops.

An overwhelming 90 per cent said loud mobile phone conversations were the most annoying part of their journeys.

Some commuters wanted them prohibited on trains, while others suggested phone and music-free "quiet carriages".

A number spoke passionately about their hatred of being forced to listen to private phone conversations and thumping bass music from earphones.

The Australian Mobile Telecommunications Association (AMTA) encourages individuals to use their mobile phones in a responsible manner and to be considerate and aware of situations where using their mobile phone might annoy others.
