Sound Insulation test according to ISO 16283

What You Will Learn

1. Measurement Setup

• How to configure the Nor145 for building acoustics measurements according to ISO 16283-1.

• How to use a smartphone or tablet for wireless remote control.

• How to create and organize a measurement project.

2. Source Room Measurements

• Measuring sound levels generated in the source room.

• Viewing frequency spectra and octave or one-third octave band data.

• Monitoring measurement results in real time on both the instrument and the mobile device.

3. Receiving Room Measurements

• Measuring sound levels transmitted through the separating building element.

• Comparing source and receiving room levels.

• Verifying measurement quality throughout the test.

4. Background Noise Measurements

• Measuring background noise in the receiving room.
• Applying automatic corrections when background noise affects the results.

5. Reverberation Time Measurements

• Performing T20 and T30 reverberation time measurements.

• Determining the acoustic characteristics of the room.

• Using reverberation time data in the calculation of standardized sound insulation values.

6. Automatic Calculations

• The video demonstrates how the instrument automatically calculates key acoustic parameters, including:

• Sound level difference (D)

• Standardized level difference (DnT)

• Apparent sound reduction index (R')

• Weighted single-number ratings such as:

  • R'w

  • DnT,w

  • Dw

7. Documentation and Reporting

• Transferring measurement data to PC software.

• Visualizing frequency curves and measurement results.

• Generating reports in accordance with relevant standards.
