Police Reform and Social Responsibility Bill

Can I check on a technical point with the noble Baroness? Clause 148(5) states: "““The notice must specify… the kind of amplified noise equipment to which the authorisation applies””." Does that mean that there will be a control on equipment in terms of the channel output of the equipment being used? It is quite a technical question, but I would have thought that some kind of estimate must be made of the channel output of the equipment. I cannot see any other way of determining what kind of equipment could be authorised.
