When a draft standard reaches a mature enough stage in the development process, the draft is posted for public review and comment before final publication. During the public review phase, feedback is welcomed from anyone who has a material interest in the draft.

Public Review and Comment 

Technical Review of the draft standard: Dynamic Range in Listener Areas – Open Now!
AVIXA Standards is seeking constructing input on the new draft standard, AVIXA A104.01:202X, Dynamic Range in Listener Areas

Standard Scope:

This Standard will:

a) Characterize the required sound pressure level from an audio system, recommend a signal-to-noise ratio (based on the anticipated environmental noise level in a venue) for different venue types, and provide measurement techniques using commonly available test equipment. 
b) Define the sound system noise level contribution.
c) Define performance requirements for audio system gain structure for a variety of venues and provide methods for verifying and reporting the levels of the audio system at various stages of the signal path.
d) Determine an appropriate testing procedure for a system to sustain the specified qualities and characteristics over a defined time scale. 
e) Define the performance metrics to measure the temporal output characteristics of an amplified audio system that will provide high quality and fidelity—a key factor in producing high intelligibility, acoustics notwithstanding. 
The procedure associated with this Standard is one of many verifications of the deployment and performance of a sound system. 

Commenting Guidelines:

• The technical review comment period closes at 12 AM EDT on September 30, 2023.
