Introduction to Acoustic Cameras


An acoustic camera is a device that uses multiple microphones to identify and visualize sound sources in a given environment. These microphones are usually arranged in a grid so that the user can create a visual “map” of the sound in a room or area. The resulting images can help architects and acousticians better understand how sound behaves in a particular environment and identify areas that need to be improved.

Acoustic cameras are becoming increasingly popular as architects and acousticians seek to create optimal acoustic environments for different spaces. From concert halls and recording studios to classrooms and office spaces, acoustic cameras have proven to be a valuable tool in understanding how sound interacts with different environments.


Acoustic cameras measure the time difference between the sound waves hitting the individual microphones in the array. This information is then used to calculate the position of the excellent source in the room. Modern acoustic cameras can capture thousands of measurements per second, providing a detailed visualization of the sound in a room.

One of the main advantages of acoustic cameras is their ability to create detailed and easy-to-understand visualizations of sound. By visually representing the sound in a room, architects and acousticians can quickly identify areas that need improvement and make informed decisions to optimize the acoustic environment.


Acoustic cameras offer several significant advantages over conventional acoustic measurement methods. They allow users to visualize sound with unprecedented detail and create an easily understandable representation of the sound. This makes it easier to identify areas in need of improvement and make informed decisions to optimize the acoustic environment.

However, like all technologies, acoustic cameras also have their limitations. For example, they cannot provide insight into the subjective sound experience or the emotional reaction of the user. Furthermore, their effective use requires a considerable amount of data processing and technical expertise.

Despite these limitations, acoustic cameras remain a valuable tool for architects and acousticians looking to create acoustically optimized spaces. Thanks to their ability to develop detailed sound visualizations and identify areas in need of improvement, acoustic cameras have become an indispensable tool for optimizing the acoustic environment of a variety of spaces.

Please read our article on coherence scanning holography and how we overcome the limitations of conventional beamforming cameras with a new technology and algorithm.

Seven Bel has taken on the challenge of breaking up the tense interrelations between image quality at low frequencies, mobility, and price by offering a radically novel technology (which is s based on a patented method called Coherence Scanning Holography (CSH)) for sound imaging: the Sound Scanner.

Utilizing this method, Seven Bel Sound Scanner is able to have a compact design and to be a cost-effective acoustic camera with more than 400 virtual microphones scanning an area of up until 5 m2.

This allows low-frequency sound events to be measured with unprecedented dynamic range and spatial resolution. Furthermore, working with Seven Bel Sound Scanner is as simple as possible. That is why it is even useful for users who has just started to do sound imaging.
