Our first meeting for 2022 is scheduled for Mon 14th February, and it will again be via Zoom.
We will be honoured to welcome Merlijn Van Veen, Senior Technical Support & Education Specialist of Meyer Sound, who will be joining us from the Netherlands.
Merlijn is also Chair of the AES Standards Task Group SC-04-03-A, which has been tasked with developing a new standard X250/AES75 “AES standard for acoustics – Measuring loudspeaker maximum linear sound levels using noise”.
Merlijn will be giving us an overview of that work, and in particular a preview of a new test signal under consideration.
Merlijn’s presentation should be an excellent follow up to Michail’s December presentation on Loudspeaker power ratings.
Further details, and bookings will be available closer to the date – stay tuned!
The next online meeting of the AES Melbourne Section will be on Monday 13th December 2021 at 7:30pm.
Michail Barabasz, of loudspeaker maker Lorantz Audio will present on the topic of:
Loudspeaker Power Ratings
…and other myths.
Modern class D amplifiers are capable of kilowatts of drive and care little for the load impedance. Can loudspeaker voice coils and suspensions handle this? Dedicated amplifier/loudspeaker combinations in active boxes can have sophisticated protection programming. How effective can this be? How should the standards for loudspeaker testing and power ratings tackle this?
On Monday October 11th the AES Melbourne Section mounted another Zoom online meeting, due to Victoria’s continuing and now world record-breaking pandemic lockdown situation.
Over thirty members and guests joined the meeting to hear Inventor and Vastigo Ltd CTO, Joe Hayes speak on his DaS AuReality loudspeaker technology in a presentation entitled:
“From Stradivarius to Speaker – technology for improvements in sound delivery and room acoustics treatment”
The DaS AuReality system claims to reduce the impact of room acoustics for the listening experience and produce a listening experience free of sweet spot limitations by using an algorithm to create Diffusion at the Source (DaS))
The next online meeting of the AES Melbourne Section will be on Monday 11th October 2021 at 7:30pm(Australian Eastern Daylight Saving Time UTC+11).
Joe Hayes, Inventor and CTO of Vastigo Ltd will describe his DaS AuReality technology in a talk titled:
From Stradivarius to Speaker
technology for improvements in sound delivery and room acoustics treatment.
We are familiar with a well-designed concert hall having clarity of performance without hard echoes and a balanced enveloping sound field. We seek to capture this in our recording and listening experiences but we often must put up with less-than-ideal acoustic environments.
What if the enveloping experience could be recreated directly from the loudspeaker without the need for the concert hall? And what if the recreated sound field did not detract from the initially arriving direct sound but could actually mask and improve the inevitable echoes and reflections of the typical less than the ideal listening environment?
