Festivals are noisy - that's part of the reason why they're fun! But noise can be a pollutant too.

Noise is regularly noted as a major environmental impact of music festivals, particularly in densely populated countries. Management of such events requires careful planning of noise abatement. Environmental Health Department of local authorities currently set and monitor noise levels during events to ensure that agreed levels are not exceeded.

Some key points to consider:
From an internet survey of 649 festival visitors the following was found with regards to attitudes to waste management at events:

This is the opinion of those visiting the festivals many of whom do actually go for the music. The picture if asking local residents may be somewhat different, as anybody who has attended a festival license hearing will be fully aware of!
Hannah Rossmorris, who deals with licensing and health & safety for Angel Music Group (Global Gathering, HiFi Festival, Escape Into The Park) refers to the noise controls that most Environmental Health Officers set and strictly enforce. Chris Kemp (Dean of Leisure & Tourism, BCUC) also describes the sound monitoring at Milton Keynes Bowl, whereby decibel readings are taken to ensure they do not exceed that set by the environmental health officer. Kemp also highlights the difficulties that organisers face when monitoring or controlling sound as weather conditions will impact upon its travel.
The survey results indicate that monitoring and control of noise is a prominent provision at festivals in the UK.
Three of the festival organisers questioned made reference to Noise pollution and local authority controls to minimise its nuisance. The control that local authorities enforce may be a reason for the lower percentage of festival-goer respondents worried about its impact. One respondent raised the point that noise pollution at festivals is only temporary. For noise disruption over a number of days it may be argued that any lasting damaging effects of this are negligible.
Generally noise complaints to Environmental Health Officers have drastically increased over the last 20 years, particularly for road traffic. However, Defra (2005) point out that a rise in complaints doesn’t necessarily mean a rise in actual noise. In another survey conducted by National Statistics showed that of twenty environmental issues, noise pollution was the least worrying to the respondents (Defra, 2002).
The issue of health and safety for the hearing of those working at events may be a more suited area for where this issue may lie, as covered by the Control of Noise at Work Regulations 2005.
