The world is too noisy. Mumbli sees a world designed for sound, where people can select public spaces based on their hearing preferences. We want to transform social spaces so that everyone can hear and be heard while they work, meet and date. We want to change how society interacts with sound at the intersection of hearing health, social spaces and technology. We picture a world where looking after your ears is just as important as cleaning your teeth, exercising or looking after your mental health. To do this, we have created the worlds first Certified for Sound programme to help businesses provide positive and inclusive spaces for all hearing preferences so they are audio accessible for everyone
