Mumbli: Noise monitoring in cafés and restaurants


Mumbli believes that over 85% of 20-40 year olds leave a bar because it is too loud for them. To change this, the British tech start-up has created a hearing wellness platform. The aim of the company is a more relaxed atmosphere. Mumbli sees the solution in intelligent IoT devices.

Mumbli: Seed round secures growth

Mumbli was given funding by the UK government in 2021 to test its noise monitoring systems. The company received positive feedback from restaurants, bars and guests and is therefore expanding its activities. A seed round contributes to the financing. This also includes a campaign on the Seeders crowdfunding platform.

Marion Marincat, Founder of Mumbli explains: “With our crowdfunding activity, we plan to further expand Mumbli from East London and establish it throughout the capital as well as in Paris and New York.” She adds, “Mumbli will not only benefit people who are sensitive to noise, but also companies that are losing a lot of money because people can’t be in spaces with excessive noise.”

Increase in revenue thanks to Mumbli

Loud places can reduce profits. Many business owners are not aware of this. According to Mumbli, many bars are losing thousands of pounds a month by failing to meet the needs of their customers. Conversely, according to the start-up, the likelihood that customers will leave the premises decreases by 76% if the atmosphere there meets expectations. With the installation of a hearing wellness platform, business owners can monitor sound levels and thus optimize the acoustic environment. From a health point of view, too, a low noise level is more beneficial.

Hearing wellness platform also supports finding measures

Beacons in Mumbli’s IoT devices continuously measure the sound level. Venue operators can quickly see where loud and quiet areas are in their building. In addition, data from the hearing wellness platform can suggest simple measures. This can include adding plants that enhance the acoustics of the room or rearranging furniture. Noise warnings can be sent via an associated app and thus prevent complaints. This protects the license of a venue. The system can also be used to generate data to enable required compliance reporting.

Mumbli brings the right sound

Users of Mumbli’s hearing wellness platform can connect it to other systems in the building via an application programming interface (API). The data can thus be used, for example, for the automatic adjustment of a sound system. There are other options too. This makes it possible to link the noise level to music playlists. As the venue gets busier, the system can trigger sounds that help set the mood.

It is beneficial for the work of the finance team to integrate the data obtained into their analysis tools. This allows searching for patterns between sound level and revenue, which helps to fine-tune operations. Companies that respond to meeting noise expectations and take necessary steps are listed on Mumbli’s “Certified for Sound Map”. This is a searchable list of venues, selected based on their noise expectations.
