We won’t hide it… At Acoustic Masters, we specialize in advanced acoustic measurements and vibration measurements, offering a wide range of services tailored to our clients’ needs. Our team uses only first-class, certified laboratory-grade measuring equipment that complies with all national, European, and international standards. We could go on and on… In short – our uncompromising approach in this area guarantees high quality and precision of results. This ensures that our studies can also be used for legal and formal purposes. Every test is backed by analysis and summarized in a report (either short or full). From each study, we create a list of conclusions and guidelines (arranged in the context of priorities and effectiveness), so that you can implement effective solutions immediately after the analysis. It’s impossible to list all the possible measurements, so below we present our service offer along with applicable standards and regulations, as well as real-life examples.

• Sound level measurement
• Noise from sanitary installations: measurement of noise generated by pipes, plumbing, and other sanitary installations in buildings.
• Noise at workstations: measurement of noise at workplaces, especially in the industrial sector, factories, production halls, and open-space offices.
• Noise from ventilation and air-conditioning systems: assessment of noise generated by ventilation and air-conditioning systems, especially in offices, shops, hotels, restaurants, and production halls.
• Noise from heat pumps: measurement of noise generated by heat pumps in residential and commercial buildings.
• Noise from machine rooms and server rooms: measurement of noise generated by noisy rooms in apartment buildings, offices, or public buildings.
• Noise in public buildings: assessment of noise in shopping malls, museums, conference centers, cinemas, theaters, or train stations.

Each country has its own regulations for assessing sound level values. In Poland, assessments are most often carried out according to PN-B-02151-2 – a construction standard concerning noise in buildings. It’s important to note that different editions of this standard apply depending on the year of issue and the period it is in force – which is why experience is crucial to ensure the correct choice of regulations for the tests performed. We have often improved measurements from other companies that were carried out in accordance with best practices but based on incorrect regulations. With us, you can be sure of support in this area.

SEE CASE STUDY: BOX IN BOX INSULATION

• Acoustic insulation measurement
• Measurement of wall and ceiling sound insulation: evaluation of airborne sound insulation (e.g., conversation through the wall, TV, barking dog) and impact sound insulation (e.g., footsteps from the floor above, moving furniture, walking upstairs) through walls and ceilings, especially in multi-family buildings, single-family homes with multiple units, offices, rooms for confidential conversations, schools, medical facilities, doctor’s offices, and law offices.
• Acoustic insulation of facades: measurement of the effectiveness of sound insulation of multi-family, office, and hotel buildings, especially in relation to outdoor noise (e.g., noisy roads, railways, airports).
• Acoustic insulation in industry: measurement of acoustic insulation in production halls, warehouses, noise-reducing boxes, booths, workshops, and factories, to protect workers from harmful noise.

Each country has its own regulations for assessing acoustic insulation values. In Poland, assessments are most often carried out according to PN-B-02151-3 – a construction standard concerning acoustic insulation in buildings. Just like with sound level assessments, different editions of this standard apply depending on the year of issue and the period it is in force. Proper selection of regulations is key, e.g., when assessing noise from a neighbor and the related formalities.
