Electroacoustic Testing - Test your Product in Real World Conditions
Smart devices such as smart speakers, hearables, wearables, robots and voice-controlled car entertainment systems are notoriously complex to test. They have numerous interfaces from Bluetooth to cloud-based/Wi-Fi, and contain much signal processing which means that their characteristics change according to “real-world” conditions such as the physical environment and background noise. Their multifunctional nature means there are many aspects of the device that may need to be tested, ranging from voice recognition to music playback or even operation as a hands-free telephone. We have many options to help ensure that we can work with you to put together a system to test your product in real world conditions.
