Research Data from Autonomous University Update Understanding of Audio Engineering (Transducer Effects on Direct Digital-to-Acoustic Loudspeaker Arrays)

By a News Reporter-Staff News Editor at Journal of Engineering -- New research on Audio Engineering is the subject of a report. According to news reporting out of Tlaxcala, Mexico, by VerticalNews editors, research stated, "Direct digital-to-acoustic converting systems do not make use of any kind of standard digitalto-analog converter throughout the electronic chain. Several systems were already reported and high values of THD and THD+N were found in the resulting wave fields together with a small minimum THD area or sweet-spot."

Our news journalists obtained a quote from the research from Autonomous University, "However, the effects of transducer transfer characteristics, sampling rates, and bit-to-transducer assignments on the resulting acoustic fields have not yet been fully described. Results are shown on THD, THD+N, and directivities describing the audio fields produced by different direct digital-to-acoustic converting array systems. Each array was conceived with a different transducer type from experimental transducer responses. A significant reduction in the overall THD and THD+N in the listening space was achieved after using a randomized bit-to-transducer assignment."

According to the news editors, the research concluded: "Practical advantages and limitations are reported that can be used in future implementations of digital-to-acoustic audio array systems."
