Based on a European standard and reissued by the International Organization for Standardization (ISO), the EN ISO 16283 standard, under the main heading "Area measurement of sound insulation in buildings and building elements," consists of the following sub-sections:
The EN ISO 16283-1 standard describes procedures for determining airborne sound insulation between two rooms in a building using sound pressure measurements. These procedures are designed for room volumes ranging from 10 m³ to 250 m³ within a frequency range of 50 Hz to 5000 Hz. The test results are used to measure, evaluate, and compare airborne sound insulation in furnished or unfurnished rooms, with or without a diffuse sound field. The measured airborne sound insulation is frequency-dependent and is converted into a single numerical quantity to characterize acoustic performance using the rating procedures in the ISO 717-1 standard.
The EN ISO 16283-2 standard describes procedures for determining impact sound insulation using sound pressure measurements with an impact source operating on floors or stairs in a building. These procedures are designed for room volumes in the 50 Hz to 5000 Hz frequency range from 10 m3 to 250 m3. The test results are used to measure, evaluate and compare impact sound insulation in unfurnished or furnished rooms where the sound field is close to a dispersed area or not.
The EN ISO 16283-3 standard describes procedures for determining the airborne sound insulation of facade elements and all facades using sound pressure measurements. These procedures are designed for room volumes in the 50 Hz to 5000 Hz frequency range from 10 m3 to 250 m3. The test results are used to measure, evaluate and compare airborne sound insulation in unfurnished or furnished rooms where the sound field approaches or does not approach a dispersed area. The measured airborne sound insulation is frequency dependent and converted to a single number quantity to characterize acoustic performance using the grading procedures in the ISO 717-1 standard.
This standard aims to estimate the sound reduction index of a facade element, such as a window, by element methods. The most accurate element method uses a loudspeaker as an artificial sound source. Other less accurate element methods use existing traffic noise. Global methods, on the other hand, aim to estimate the outdoor/indoor sound level difference in real traffic conditions. The most accurate global methods use real traffic as the audio source. In cases where the traffic noise in the room is insufficient, a loudspeaker is used as an artificial sound source.
The element loudspeaker method gives, under certain conditions, an apparent sound reduction index comparable to the sound reduction index measured in laboratories according to the ISO 10140 standard. This method is the preferred method when the purpose of the measurement is to evaluate the performance of a particular façade element relative to its performance in the laboratory.
Among the numerous test, measurement, analysis and evaluation studies it provides for businesses in various sectors, our organization also provides area measurement services for sound insulation in buildings and construction elements, within the scope of EN ISO 16283 standard, with its trained and expert staff and advanced technological equipment.
