Atlantic Air provide a comprehensive service in relation to the assessment and testing of building sound insulation performance. As SITMA Registered Testers (UK & NI) and SITRI Registered Testers (ROI) we are competent to undertake pre-completion testing on non-detached houses, apartments, rooms for residential purposes, schools and other buildings.
Our experienced testers collect field measurements in accordance with ISO 140 and ISO 16283 (all parts) as required in order to ensure compliance with current Building Regulations i.e. Technical Booklet G 2012 (UK & NI) and Technical Guidance Document E 2014 (ROI). We will liaise directly with Building Control and/or the Assigned Certifier in order to establish and agree the required number of tests, so that we can provide a stress-free service and an accurate quotation with no hidden costs. The images used for ‘Airborne Sound Insulation Testing’ and ‘Impact Sound Insulation Testing’ need to be switched around and made equal in size.
Sound testing or acoustic testing as it is also known with regard to buildings is the measurement of the sound level difference between two rooms separated by party walls and/or floors between dwellings and rooms such as classrooms, hotel rooms, offices etc. There are two ways of testing acoustic insulation of separating elements;
The airborne test measures the resistance to the passage of airborne sound through a separating wall or floor. Using a high powered multi directional loudspeaker we will generate 123dB of ‘pink’ noise on one side of a separating wall or floor (Source Room). Using a UKAS calibrated Sound Level Meter and Class 1 Microphone we will take a series of measurements to determine the sound pressure level in the Source Room. We will then move to the opposite side of the separating wall or floor (Receive Room) and measure the sound pressure level, reverberation time and background noise level. This then allows us to calculate the sound level difference between the two rooms under test (DnT,w) and compare it to the performance requirements for that separating element.
The impact test measures the resistance to the passage of impact sound through a separating floor. Using a UKAS calibrated Tapping Machine that contains five equal size hammers, we can generate a continuous and stable impact sound on the floor (Source Room). Using a UKAS calibrated Sound Level Meter and Class 1 Microphone we will measure the sound pressure level, reverberation time and background noise level in the room below (Receive Room). This then allows us to calculate the weighted standardised impact sound level (L’nT,w).
For Acoustic Testing to take place;
Many industrial processes generate airborne contamination which can be hazardous to human health. To mitigate employee exposure hazardous airborne contaminants, it´s important to make sure that dust particles and/ or smoke fumes are extracted at the source before they reach the breathing zone.
The most effective solution for removing and mitigating dust and/ or fume exposure is close or at-source extraction. Extraction arms, sometimes called snorkels, vary in diameter and length, can be positioned from 150mm – 350mm from the point of dust/ fume generation and typically have an extraction volume of 850 – 1700 m³/h. The variation in arm design and style is so there is a model that can be applied to different applications where the arm needs to fit within a small workspace or instances where the arm must be able to reach to distances of 5 meters or more.
Ventilation is a primary solution step to mitigate employee welding fume exposure. Because welding fume is a thermal process, the particulate is suspended in the ambient air space. When the fume plume cools, the particulate settles to the workspace. It builds up on workstations and can infiltrate machinery and electronics causing damage and creating the need for additional housekeeping, which can add another layer of maintenance and overhead cost. Atlantic Air can source and install a wide range of welding fume extraction arms in different designs with full flexibility and are easy to position to fit many applications.
