Building acoustics measurements verify how effectively a structure controls and manages sound. In residential, commercial, and public buildings, testing may cover airborne sound insulation between rooms, impact noise from floors, façade insulation, and reverberation characteristics. These measurements provide evidence that the building meets applicable acoustic requirements and performs as intended for its occupants.
Acoustic testing is also essential in public environments where announcements and emergency voice alarms must remain understandable across different areas. Room dimensions, construction materials, furnishings, occupancy, and background noise can all influence the result. Acoustic consultants, building engineers, testing laboratories, contractors, and facility managers use sound level meters, analyzers, acoustic sources, and software to assess completed buildings, verify construction quality, investigate complaints, and document compliance.
Class 1 sound level meters and analyzers provide the measurement foundation for assessing building acoustic performance. With 1/1 and 1/3 octave band analysis, reverberation time measurements, and STIPA functionality, the instruments support testing across a broad range of applications. Users can evaluate airborne sound insulation, impact sound insulation, façade insulation, and room reverberation characteristics using measurement data suited to professional acoustic assessment. The same platform can also support speech intelligibility testing in public spaces. This helps acoustic consultants, laboratories, and building professionals gather the evidence required to compare measured performance with regulatory requirements and document the acoustic behavior of residential, commercial, and public buildings.
Building acoustic measurements often take place in occupied or operational environments, where testing must be accurate without unnecessarily interrupting daily activities. Guided measurement workflows help operators apply a consistent approach across rooms with different geometries, materials, furnishings, and occupancy conditions. Dedicated sound sources, including omnidirectional loudspeakers, tapping machines, and façade insulation test equipment, support controlled airborne, impact, and façade sound insulation measurements. Intelligent tagging records the source room, receiving room, background noise, reverberation, measurement position, and sound source location. This improves repeatability, preserves the context of each result, and helps teams complete structured tests with better control over the time and disturbance involved.
Large building acoustics projects can generate many measurements across multiple rooms, positions, and test conditions. Clear data classification is therefore essential for efficient analysis and reporting. NS-SIS software supports the automated processing of building acoustic measurements according to ISO 16283, ISO 717, and ISO 3382. It can calculate relevant acoustic indices and organize results according to the recorded measurement structure. Professional report generation gives users a consistent way to present test conditions, measurement data, calculated values, and final results. This reduces manual processing and helps acoustic consultants, laboratories, and building teams move from field measurements to documented conclusions with less risk of transcription or classification errors.
Speech intelligibility testing shows whether announcements and emergency voice alarm messages can be understood in the areas where they are needed. Integrated STIPA analysis, compliant with IEC 60268-16, supports fast and repeatable verification of communication systems under different acoustic conditions. Built-in test signal generation allows operators to perform measurements without relying on separate signal sources. The approach is suited to complex public spaces where room reverberation, background noise, geometry, and occupancy can affect how clearly speech is heard. Results help consultants, facility managers, and system integrators identify areas that require attention and verify whether voice communication performs as intended across the building.
More than 20 million people are highly annoyed and almost 7 million people are highly sleep disturbed by long-term exposure to transport noise in Europe.
