Our laboratory supports companies in questions related to product development and testing of building products, furniture, air products and machinery. Below are our most common testing services, some of which are FINAS accredited.

Detailed information about the acoustics laboratory spaces and services can be found here. Detailed updated dimensions are available here.

Laboratory Tests in the Reverberation Room:

• Airborne sound insulation: doors, walls, windows, ventilation grilles, etc.
• Sound absorption coefficient (room method): acoustic panels, partitions, furniture, etc.
• Reduction in impact sound level: floor coverings
• Impact sound insulation: floor structures
• Sound power level and noise emission: fans, machines, etc.
• Flow noise of duct products: control dampers, terminal devices, etc.
• Sound attenuation of duct products: silencers, terminal devices, etc.
• Speech level reduction: phone booths, workstations, meeting pods, etc.
• Accreditation certificate
• Delivery instructions for the laboratory

Material Tests for Small Components

• Reduction in impact sound level: floor coverings
• Dynamic stiffness: underlay materials, partition studs, etc.
• Sound absorption coefficient (tube method): small samples

Noise Control Design and Consulting Related to the Above

Our acoustic laboratory is continuously involved in developing acoustic solutions for companies.

Best of all, some results are published for everyone to use. See an example of results published by Akukon Oy regarding absorptive suspended ceilings for performance spaces that also work at low frequencies. https://www.akustinenseura.fi/wp-content/uploads/2023/11/akustiikkapaivat_2023_s281.pdf
