To require a test, the property must have either a separating wall or floor with another property. Depending on which element is present, it will require either an Airborne or Impact test. An airborne test is carried out on both walls and floors, and impact on floors. Both methods of testing are measured between habitable rooms (Bedrooms, Living Room, Kitchen, etc.)\u003C\u002Fspan>\u003Cspan data-ccp-props=\"{}\"> \u003C\u002Fspan>\u003C\u002Fp>\n\u003C!--more-->\u003Cp>\u003Cspan data-contrast=\"auto\">The majority of properties that require this test are flats, semi-detached, and terrace houses.

As well, the engineer calibrates the meter before and after each test to ensure the meter hasn’t varied from its calibrated state. \u003C\u002Fspan>\u003Cspan data-ccp-props=\"{}\"> \u003C\u002Fspan>\u003C\u002Fp>\n\u003Cp>\u003Cspan data-contrast=\"auto\">So, there are two types of pass rate, the Airborne and the Impact, which we previously outlined.

The purpose of an airborne test is to measure the sound level transmitted through the air from one dwelling to another. The loudspeaker outputs white noise on one side of the partition, while measurements are taken with a sound meter on the opposite side. This then allows us to calculate how many decibels (dB) are lost through the partition.\u003C\u002Fspan>\u003Cspan data-ccp-props=\"{}\"> \u003C\u002Fspan>\u003C\u002Fp>\n\u003Cp>\u003Cspan data-contrast=\"auto\">This test mimics the effects of people talking, playing music or watching TV.\u003C\u002Fspan>\u003Cspan data-ccp-props=\"{}\"> \u003C\u002Fspan>\u003C\u002Fp>\n\u003Cp>\u003Cspan data-contrast=\"auto\">An impact test is only carried out on floors\u002Fceilings that divide dwellings. This is to measure the amount of noise transmitted directly through an impact to the separating construction. For this, a tapping machine is used, which consists of multiple metal weights continuously tapping the floor to create an impact noise. We then measure how much sound passes through the floor\u002Fceiling using the same sound meter on the other side.\u003C\u002Fspan>\u003Cspan data-ccp-props=\"{}\"> \u003C\u002Fspan>\u003C\u002Fp>\n\u003Cp>\u003Cspan data-contrast=\"auto\">This mimics the sound of people walking around and moving things, such as furniture.\u003C\u002Fspan>\u003Cspan data-ccp-props=\"{}\"> \u003C\u002Fspan>\u003C\u002Fp>\n\u003Cp>\u003Cspan data-ccp-props=\"{}\"> \u003C\u002Fspan>\u003C\u002Fp>",0,"max-w-6xl mx-auto","09-08-2022","2026-01-27T17:57:47.000000Z","2026-01-27T17:57:48.000000Z",{"id":51,"meta_title":9,"meta_description":52,"seoable_id":5,"seoable_type":53,"keyword_focus":54,"search_intent":10,"cornerstone_content":24,"canonical_url":55,"meta_robots":56,"og_title":9,"og_description":52,"og_image":57,"og_type":58,"og_url":10,"twitter_card":59,"twitter_title":9,"twitter_description":52,"twitter_image":57,"schema_markup":10,"extra_meta":10,"ai_field_locks":10,"insights":10,"serp_insights":10,"hreflang_alternates":10,"json_ld":10,"sitemap_changefreq":60,"sitemap_priority":61,"created_at":48,"updated_at":62},128,"What is a Sound Test?
