Factors Impacting Manufacturing Testing of Audio Products

When determining a manufacturing test strategy for an audio device, you must look at ways to balance costs – specifically the cost of test against the cost of failure. Although this seems simple in concept, it involves several variables for both “cost of test” and “cost of failure.” There is a practical financial question of what measurements should be taken for the quality control of audio products and/or devices incorporating audio, and where those tests should occur. This application note will focus on specific manufacturing test strategies and objectives, and their associated costs.
