Use of PA systems on stands must be requested in writing to the Organisers. Exhibitors showing films or creating excessive noise or using audio visual aids which disturb adjacent exhibitors may be asked to cease such activities in the interest of the overall exhibition. Excessive noise as deemed by the Organisers to cause a disturbance is not permitted. The Organiser shall be regarded as the sole arbiter in the case of dispute and the Exhibitors shall follow the directions of the Organiser in order to resolve any such dispute.

The maximum permissible total sound level in any area of the show is 82dB (slow), measurable at a distance of three (3) metres from the source of the sound using a directional decibel meter.
