What is often the focus of laboratory studies during preclinical testing of electroacoustic devices?

During preclinical testing of electroacoustic devices, the primary focus is on assessing safety and functionality. This stage of testing is critical as it involves rigorous evaluation under controlled conditions to determine whether the device operates as intended and does not pose any harm to users or patients.

Establishing safety ensures that the device meets regulatory standards and protects users from potential risks that could arise from its use. Functionality assessments verify that the device delivers its intended performance and effectively meets the clinical or consumer needs it is designed for. This comprehensive evaluation serves as a foundation for subsequent steps in the regulatory approval process, ultimately guiding the transition to clinical trials where real-world usability is tested in human subjects.

In contrast, considerations such as market potential or user satisfaction are not typically prioritized during laboratory studies, as these factors become more relevant in later stages of development after safety and functionality have been confirmed.
