The Government advice regarding playing music says,
" All venues should ensure that steps are taken to mitigate the
increased risk of virus transmission associated with aerosol
production from raised voices, such as when speaking loudly or
singing loudly, particularly in confined and poorly ventilated
spaces. This includes, but is not limited to, lowering the volume
of background music, and refraining from playing music or
broadcasts that may encourage shouting, particularly if played
at a volume that makes normal conversation difficult. Evidence
on the most effective steps that can be taken to limit the
transmission of the virus continues to be regularly reviewed.
This guidance may be updated in the future in response to
changing scientific understanding."
It might be worth pointing that out to the council officials.
