CAE - Acoustic Camera - Customized Microphone Arrays
You already have a specific concept for your array? We implement your idea exactly how you want it. Our specialists can certainly advise you so that your custom microphone array meets the application needs precisely. There are no limits for your acoustic camera. Not only is it possible to create a mobile solution but integration in walls or whole rooms is no problem. Choose between analog and digital technology and determine the required size, form and channel number for your application together with our experts.
- Size of the acoustic camera: according your needs
- Specifications of the acoustic camera: according your needs
- Number of microphones of the acoustic camera: according your needs
- Recommended frequency range for the acoustic camera: according your needs
- Production material of the acoustic camera: according your needs
- Weight of the acoustic camera: according your needs
