Test ~ General

The purpose of electronics testing in audio systems is to ensure quality control and consistency in the manufacturing process. The outcome is to verify that audio devices meet the product design specifications and performance requirements¹.

Key aspects of audio electronics testing include:

• Level: Checking the output level to ensure it matches the expected performance.
• Frequency Response: Ensuring the device accurately reproduces the audio signals across the intended frequency range.
• THD+N (Total Harmonic Distortion plus Noise): Measuring the unwanted harmonic frequencies produced by the device that can affect sound quality.
• Phase: Checking the phase alignment of audio signals.
• Crosstalk: Assessing the isolation between different audio channels to prevent interference².

The outcome of such tests is to catch any audible defects like rub & buzz, loose particles, or other issues that can affect the consumer’s perception of audio quality. This helps in minimizing warranty repairs and maintaining customer satisfaction³. Additionally, it aids in process improvement and product enhancement by identifying areas where the manufacturing process can be optimized¹.
