How combining noise monitoring with video and audio can help keep your projects on track

Construction and engineering (C&E) is a growing industry, currently generating nearly $10 trillion in revenue or about 6% of global GDP. Covering cities, ports, infrastructure and mining just to name a few sub-sectors, C&E plays a huge role in driving the economy. However, at the rate at which the industry is growing, technological advancement in the space is often derided as being behind. Although this may be true in some areas, it’s not the case in environmental monitoring.

City construction image Environmental monitoring has long been a concern in industries such as airports and extends beyond just noise measurements to community engagement, that is, managing community relations around environmental parameters to build social license and avoid operating delays. Across all phases of C&E, environmental monitoring is becoming critical not just as a compliance requirement but as an intrinsic part of operating and project delivery.

In high density urban locations, one environmental parameter that’s important to measure is noise. Typically a compliance requirement, noise measurements allow organisations to show that they are within the operating limits. However, capturing noise data is just the tipping point. The data can be enriched with additional parameters such as video, which can provide smarter insights that can inform business decisions and improve project delivery.

Until recent years, surveillance video cameras haven’t been suitable for remote cloud-based storage systems due to the bandwidth required to transmit data. Advances in both camera and compression technology now means that we can utilise video footage and/or still photos to enhance how we monitor environments by combining it with noise measurements.

By combining noise measurements with video or still photos, you can enhance the richness of the data in order to identify the source and categorise the sound. What does this mean for C&E projects? It means that you will be able to easily identify what’s causing the disturbance around your project and if the source of the noise is yours or in fact, someone or something else. The data allows you to dispute any complaints that may occur and reduce delays to the project.

Our latest conference paper describes the techniques involved with this approach, how it’s evolved over time, including the learnings and provides case studies highlighting best practice in combining video, audio and noise data in state-of-the-art noise monitoring solutions.
