Why Engineers in Building Acoustics and Environmental Noise Need an Acoustic Camera

In the world of building acoustics, it is crucial to precisely locate sound sources and quickly identify problem areas. Traditional measuring tools often offer only limited insights into these complex acoustic phenomena. This is where the Sound Scanner comes into play. With its ability to precisely locate sound sources and quickly identify problem areas, it sets new standards in architectural acoustics.

Unlike traditional measuring tools, the Sound Scanner not only provides indirect clues but also enables direct and accurate localization of sound sources in a room or on a construction site. This allows for targeted troubleshooting and optimization, saving time and costs in the process.

Defective Partition Wall

Productivity at workstations near meeting rooms can be significantly impacted if partition walls fail to provide the expected level of sound insulation. By using an omnidirectional speaker in the meeting room, the Sound Scanner locates weaknesses in problematic frequency bands, e.g. in the 500Hz octave band on the left side and in the 2kHz octave band on the right. The acoustic image reveals a major weakness where the glass pane is fitted into the wooden frame, helping to communicate effective measures for addressing the issue.

Defective Ceiling Connection

The Sound Scanner helps quantify primary and secondary weaknesses of the partition wall in a meeting room. Using an omnidirectional speaker in the meeting room, the Sound Scanner locates insufficient insulation on the opposite side of the partition wall in the 1kHz octave band. The acoustic image shows a 6dB difference between the dominant source at the ceiling connection near the door frame on the left and leaks at the glass pane fitting on the right. This information allows for the implementation of targeted measures and effective rework to improve sound insulation.

Airborne Sound Bridge in Drywall

Analyzing the causes of unmet sound insulation is challenging because relevant areas may not be easily accessible. The acoustic image reveals sound coming from the omnidirectional speaker source in the adjacent room through the perforated ceiling. The root cause is due to an inadequately insulated pipe penetrating the drywall behind the ceiling construction. Sound pressure level measurements on the surface fail to reveal the root cause and show elevated values in the corner of the room – leading to misinterpretations pointing to a weak spot at the facade connection.

Ineffecive Parting Line

The reasons for failing to meet impact sound insulation standards can be varied. In the frequency range below 1 kHz, subjective assessment of structure-borne sound transmission through the floor, wall, or ceiling, or airborne sound transmission through door leaks, is particularly challenging. Using a tapping machine as an excitation source in the adjacent room, the Sound Scanner provides clear insights into how impact sound comes into the room – on the right: floor radiation in the 250Hz octave band, on the left: door leak in the 1kHz to 4kHz octave band. Reworking the parting line is reuired to reduce structure-borne sound transmission through the floor in the problematic 250Hz octave band.

Powerful Features
for Your Post-Processing

Our desktop app offers powerful functionalities for detailed evaluation of data captured with the acoustic camera on-site. With a variety of specific and high-performance features, it enables comprehensive analysis and provides you the opportunity to examine the results in detail.

Seven Bel's Desktop App Feature "Map and Probe" for the Building Acoustics

Map and Probe

The Map and Probe feature allows users to select specific areas in the acoustic image and directly compare them in terms of their frequency content and sound power levels.

Thus, the time-consuming analysis of frequency ranges, in which certain excitation sources operate, becomes a thing of the past, enabling you to achieve a quicker quantitative assessment of the contributions of components and areas.

What distinguishes Public and Private Cloud infrastructures for computing acoustic images?

Public cloud users send their data to the cloud, relying on an internet-capable data connection. In contrast, private cloud users transfer data to a local high-performance laptop using a local WiFi connection.

The computation time for acoustic images is generally comparable between these configurations. The private cloud package is ideal for users without an internet-capable data connection at the measurement location who prefer to analyze results on-site.

Can I use my own mobile devices?

The camera characteristics of the provided mobile device are measured and compensated. While the mobile app can technically be installed on other Android devices (Android operating system version 10.0 or higher), conducting measurements with such devices is not recommended.

This is because the localization accuracy cannot be guaranteed due to missing information on the camera module. However, any compatible mobile device can be used for importing and analyzing measurement data recorded with the provided mobile device.

Can I use my own laptop?

The Private Cloud configuration includes a dedicated, pre-configured high-performance laptop for efficient computation of acoustic images with minimal response time.

Please note that we do not support the installation of the compute service on other equipment.

What additional costs arise besides the annual software license?

For Public Cloud users, an internet-capable data connection is required, and additional costs for metered data connections (e.g., mobile data) should be considered.

What is the average recording time for a measurement?

In many situations, successful localization of acoustic sources can be achieved with a recording time of only 5-10 seconds per measurement.
