Tell us what you think
You have taken many steps to improve noise control. To make sure those actions are still effective you need to:
Ensure that band members understand why they need to follow instructions on control measures. Provide additional training if necessary.
Review the results of hearing health checks to see how well the noise controls are working
Ensure that those who need to use hearing protection are doing so correctly and consistently.
Review the steps you have taken (see What do you need to do?) before major changes of programme, repertoire or venue.
