ANSI CTA 2051:2017 pdf download.Personal Sound Amplification Performance Criteria.
ANSI CTA 2051 includes technical performance metrics and associated target values for consumer products that provide personal sound amplification and/or enhancement to a user. Products shall meet the stated requirements to be considered as compliant to this standard. Personal sound amplification may be a single function within a larger set of device capabilities.
Descriptions of feature specific device performance baselines and metrics of measurement are described. Device performance capabilities have been divided into feature specific sub-sections that identify:
required minimum performance values, metrics of measurement necessary to identify feature specific performance values, and methods of reporting prescribed to each feature specific value.
