BS EN ISO 140-4:1998 Overview

Title and Scope: This BS EN ISO 140-4:1998 , titled “Acoustics. Measurement of sound insulation in buildings and of building elements. Field measurements of airborne sound insulation between rooms,” specifies methods for field measurements of airborne sound insulation in buildings. It focuses on the sound insulation properties of interior walls, floors, and doors between two rooms under diffuse sound field conditions. This standard helps determine the protection provided to occupants by assessing the sound insulation levels between different spaces in a building.

Key Features:

  1. Measurement Methods:
    • The standard provides detailed methods for measuring the airborne sound insulation between rooms. It includes procedures for setting up and conducting these measurements to ensure consistency and accuracy.
  2. Frequency-Dependent Values:
    • It specifies that the measured sound insulation values are frequency-dependent. These values can be converted into a single number that characterizes the acoustic performance of the building elements by applying ISO 717-1.
  3. Comparison and Compliance:
    • The results obtained from these measurements can be used to compare the sound insulation performance between different rooms and to assess whether the actual sound insulation meets specified requirements.

Applications: This standard is essential for professionals involved in building acoustics, including architects, engineers, and construction managers. It is used to ensure that buildings meet required sound insulation standards, enhancing the comfort and privacy of occupants.

Importance: Understanding and applying the methods outlined in BS EN ISO 140-4:1998 is crucial for ensuring that buildings provide adequate sound insulation. Proper implementation of this standard contributes to better acoustic comfort in residential and commercial buildings, reducing noise pollution and improving the quality of indoor environments.
