Helping to improve the working environment

Solution: IoT sound monitoring
Industry:  Commercial

The brief

A leading office space provider approached cThings to help resolve an issue with poor sound conditions within their latest flagship building. Shortly after the opening of the building, it became apparent that sound levels within the building were causing a poor working environment for staff. The poor acoustic conditions resulted in meeting rooms being perceived as unsuitable due to background noise and causing employees to report a lack of productivity due to the disruption.

The building operator had conducted several acoustic surveys to identify the cause of the issue and take action to retrofit soundproofing. After the improvements were made, however, the building occupants didn’t notice any change and complaints of disruptive noise continued.

We were requested to deploy sound monitoring equipment to collect and analyse the data before and after the installation of new soundproofing measures, in order to determine the effects. Another aim would be to identify problem areas within the building in order to help determine the specification of future soundproofing modifications.

The solution

cThings deployed Sound Sensors throughout the building. These included meeting rooms, open spaces, and corridors. The sensors are battery-powered and use wireless LoRaWAN communication. This meant the installation, setup and commissioning were completed at a low cost and within a day.

Once the sensors were configured to send data to the cThings Cloud, this allowed us to create a digital twin of the building using our flexible hierarchy enabling us to model the acoustic conditions within the building. The customer also benefited from being able to create and download reports to undertake their own analysis.

Using the cThings Cloud empowered the customer to visualise and understand the conditions of their buildings, before and after the installation of additional soundproofing. For the first time, the customer had numerical evidence to determine the effects of the soundproofing.

The results

Following the installation of the sensors and the implementation of the dashboard the customer was able to identify areas of the building that were suffering from the amplification of background noise.

Once these areas were highlighted, the customer targeted these areas for additional soundproofing. With the assistance of external consultants using the collected data, the customer was able to identify high-decibel areas of the building, which in turn were causing other areas to suffer from noise pollution by contagion. These areas were also targeted with the rollout of soundproofing. At the conclusion of this installation, the acoustic performance of the building was significantly improved

The benefits

Low-cost solution

The sensors are battery-powered and use wireless communications which leads to quickly deployed and low-cost projects

Cost savings installation

The sensors can be used to help plan soundproofing or the acoustic performance of buildings. Helping to reduce the cost of retrofitting buildings and to assist in the design of new buildings.

Key performance metrics

The sensors record key parameters such as peak or average sound levels allowing for detailed analysis and to help create the best environments for offices, homes, and public spaces.

Expandable network

The cThings sound monitors also feature secondary sensors to help determine the environmental conditions within the building (temp/humidity/light) and occupancy. Allowing you to understand your building in more detail.
