Interpreting Field Measurements of Directivity Factor and Their Relation to the Proposed Standard Method of Measuring the Directivity Factor of Loudspeakers Used in Commercial Sound Work
Increasingly accurate results attend the field measurements of critical distance. Multipliers and divisors of critical distance have been sufficiently identified to allow usable correlation between the proposed anechoic chamber method and the semi-reverberant field measurements. Various anomolies regarding geometric Q, maximum Q, relative Q, and a will be discussed. A more usable critical distance equation will be presented. A product goal evolved from these techniques will be suggested.
