About these reports
Noise impact assessment. A noise impact assessment looks at noise affecting a site, or noise a new use would create, so the council can judge whether people will be disturbed.
Sound insulation testing. Pre-completion sound testing checks that the separating walls and floors between homes block enough airborne and impact sound to meet Part E of the Building Regulations.
