What noise sounds very much like an untuned television or radio (before they became digital!). Pink noise is very similar, but a level of control is placed on the noise to ensure frequency bands output a similar amount of energy.<\/p><p>We place a speaker into the source room, turn it up to 100dB (or louder, if we can) and measure the noise output in the source room from that speaker. It can get very loud so ear protection is a must. We call this measure L1 (L stands for Level, so it\u2019s the Level in room 1). We then leave the speaker where it is, move to the receive room and measure the amount of noise in the receive room. We call this measurement L2. In theory we already have our sound insulation, we simply take the noise we made in L1 and takeaway the noise we measured in L2, this gives us our <strong>sound insulation.<\/strong><\/p><\/div>\n\t\t\t\t\t\t\t\t\t<div class=\"elementor-tab-title elementor-tab-mobile-title\" aria-selected=\"false\" data-tab=\"2\" role=\"tab\" tabindex=\"-1\" aria-controls=\"elementor-tab-content-7722\" aria-expanded=\"false\">Impact Sound Insulation Tests<\/div>\n\t\t\t\t\t<div id=\"elementor-tab-content-7722\" class=\"elementor-tab-content elementor-clearfix\" data-tab=\"2\" role=\"tabpanel\" aria-labelledby=\"elementor-tab-title-7722\" tabindex=\"0\" hidden=\"hidden\"><p><strong>Impact sound insulation testing<\/strong> is slightly different. We take what we call a \u2018tapping machine\u2019, which has 6 precise metal weights which drop from a very precise height onto the floor mimicking the effect of a child running very fast and place the machine at 45 degrees to the axis of the room. The 45-degree axis is done to ensure the tapping machine isn\u2019t placed directly onto a joist which could mask or dampen the noise. The tapping machine is eventually placed in 4 different positions too.<\/p><p>Because the tapping machine is highly calibrated and controlled, we only measure the noise it generates in the receive room.

Machines and tools used on-site could in theory make the noise in the receive room higher which would give a false reading for the wall. It is important to keep the site as quiet as possible during measurements. Sometimes this will mean shutting a site down or testing out of hours to ensure a quiet site. We measure the background noise level in the receive room and can apply a small correction where some background noise does influence the test, however, this is limited to 6dB so any additional noise will be taken as poor performing walls.<\/p><\/div>\n\t\t\t\t\t\t\t\t\t<div class=\"elementor-tab-title elementor-tab-mobile-title\" aria-selected=\"false\" data-tab=\"2\" role=\"tab\" tabindex=\"-1\" aria-controls=\"elementor-tab-content-2342\" aria-expanded=\"false\">Reverberation Time Measurement<\/div>\n\t\t\t\t\t<div id=\"elementor-tab-content-2342\" class=\"elementor-tab-content elementor-clearfix\" data-tab=\"2\" role=\"tabpanel\" aria-labelledby=\"elementor-tab-title-2342\" tabindex=\"0\" hidden=\"hidden\"><p>But can\u2019t I just fill the room with egg boxes to improve my sound insulation?
