BS EN ISO 140-7:1998 Overview

Title and Scope: BS EN ISO 140-7:1998, titled “Acoustics. Measurement of sound insulation in buildings and of building elements. Field measurements of impact sound insulation of floors,” specifies methods for field measurements of impact sound insulation in buildings. It focuses on the sound insulation properties of floors, helping determine the protection provided to occupants by assessing the impact sound insulation between different floors within a building.

Key Features:

  1. Measurement Methods:
    • The standard provides detailed procedures for measuring impact sound insulation using a standardized tapping machine that simulates footsteps. The sound pressure levels are measured in the receiving room, and the results are used to calculate the normalized impact sound pressure level.
  2. Frequency-Dependent Values:
    • The standard specifies that measured values are frequency-dependent. These values can be converted into a single number rating to characterize the acoustic performance of the floors, applying ISO 717-2.
  3. Comparison and Compliance:
    • Results from these measurements can be used to compare the sound insulation performance of different floors and to assess compliance with specified acoustic requirements, such as building regulations.

Applications: This standard is essential for professionals in the field of building acoustics, including architects, engineers, and construction managers. It ensures that floors in buildings meet the required sound insulation standards, enhancing the comfort and privacy of occupants by reducing impact noise transmission.

Importance: Understanding and applying the methods outlined in BS EN ISO 140-7:1998 is crucial for ensuring that building floors provide adequate impact 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.
