We design sound for a broad range of physical environments and products.

Sound Design & Audio Branding

Designing with sound

At Efterklang we have extensive knowledge and experience in developing successful sound architecture, sound design and audio branding for physical spaces and digital products. We design sound for a broad range of environments such as offices, hospitals, shopping malls, banks, hotels, restaurants, city parks, playgrounds and products such as autonomous vehicles, kitchen appliances, smart home products and all sorts of UI’s. 

We customize each case based on its existing acoustic and technical preconditions, as well as careful consideration of the user and their activity in the environment. Central to our process is the psychoacoustic perspective: The science of how humans perceive and respond to sound.

In our state-of-the-art studios we produce all sound content, ranging from a short start up sound for an electric vehicle, a relaxing soundscape for a lobby or a full scale sound concept for a retail environment with 20 different sound zones and over 100 hours of sound content. 

By covering the entire process from pre-study and concept to hardware solutions and sound content, we can ensure the best possible result in fine-tuned harmony with the acoustics, the people and any pre-existing sounds in the space. Regardless of the project’s size, our promise is always a user-friendly solution with a human centric focus.
