Prism Sound Introduces Wednesday Webinar Events

Product developers and engineers working in the consumer electronics, automotive and broadcast industries now have the opportunity to tune in to a series of free webinars organised by Prism Sound. The Wednesday Webinar series starts on 24 June with Mobile Music: a webinar presented by Prism Sound's Dan Foley on measuring the acoustic and electronic performance of portable music players. This event considers whether portable-music-player customers are in danger of suffering hearing damage.

Attendees will learn how to make accurate, reliable and repeatable measurement of headphones, earphones and portable-music-player electronics. These measurements are vital in ensuring that customers are protected from excessive loudness but still enjoy high-quality sound. Topics covered in the webinar will include: the present standards environment regarding human safety; fixtures for testing circumaural, supra-aural and supra-concha headphones, ear buds (intra-concha) and insert earphones (intra-canal); and test techniques for headphones, ear buds and portable players.

The second Wednesday Webinar session, which takes place on 8 July, will focus on the broadcast industry, with Prism Sound's Doug Ordon explaining test strategies for reliable, high-quality digital audio in HD radio. This webinar will ask the question: is your digital audio stream plagued by pops and glitches? It will also ask: is your sound turning off your audience? Attendees will learn how to build high-quality, reliable digital audio distribution networks free from annoying pops, glitches and drop-outs.

Topics covered will include: the AES3 format; how to understand the eye pattern; reliability and connectivity issues for AES3 digital audio; and test techniques for transmission reliability in bit- and non-transparent signal chains. Prism Sound is running its Wednesday Webinar series on the second and last Wednesday of every month. Future topics will cover audio testing for the live sound environment, for microphones and amplifiers and for automotive products. Prism Sound will run two sessions on each topic - the first starting at 09.00 EDT and the second at 13.00 EDT.

Sessions will last for 20 minutes and there will be an additional 10 minutes for questions. The sessions are free to attend but spaces are limited. Those interested can register via the Prism Sound website at
