ISO 717-2 Rating of Sound Insulation Impact Test
The ISO 717 series specifies methods for the measurement and assessment of sound insulation in buildings. Among these, ISO 717-2 focuses on the rating of impact sound insulation using a single impulse sound source. This service is critical for ensuring that construction materials meet the necessary acoustic performance standards, particularly relevant to residential and commercial building environments.
The test involves generating an impulsive noise from one side of a partition or floor/ceiling assembly and measuring the resultant sound pressure levels on the other side. The objective is to determine the impact sound insulation class (Ra) which quantifies how effectively materials reduce impact noises, such as footsteps or furniture movements.
Accurate measurement of these parameters requires precise instrumentation including a noise generator with controlled impulse characteristics and a sound level meter capable of capturing high-frequency components. The test setup is designed to simulate real-world conditions while maintaining strict control over variables like room dimensions and background noise levels.
The process begins by preparing the specimen, which typically consists of a floor or ceiling assembly supported on resilient mounts. Once prepared, the system is calibrated according to ISO 140-3, ensuring accurate measurement across all frequency ranges. Impulse sounds are then generated using a standardized device, and the resulting sound pressure levels are recorded at multiple locations.
The data collected during testing provides insights into the effectiveness of different materials in reducing impact noise. This information is crucial for architects, builders, and engineers who need to ensure compliance with local building codes and international standards such as ISO 140-3 or EN 62379.
Understanding the results allows stakeholders to make informed decisions about material selection, design modifications, and potential improvements. For instance, if a particular floor finish does not meet the required Ra rating, adjustments can be made to enhance its acoustic performance. This might involve adding additional layers of insulation or selecting different materials altogether.
Regular testing ensures ongoing compliance with changing regulations and helps maintain high-quality standards in construction projects. By leveraging this service, clients benefit from enhanced soundproofing capabilities, improved occupant comfort, reduced noise pollution, and compliance with relevant international standards.
