This British Standard gives recommendations and guidance for the design,
specification, maintenance and operation of permanently installed sound
systems used for emergency purposes at sports venues.
It aims to ensure that, in an emergency, voiced messages are intelligible in all
parts of the sports venue to which the public have access, no matter what type
of event is taking place, as well as those areas outside the sports venue that the
system is intended to serve.
This standard applies irrespective of whether or not a special sound system is
installed for an event.
