TCLH - Mission:

The committee works to ensure that the AES membership has the opportunity to learn of relevent new transducer technology as it develops, with an emphasis on sound field generation from loudspeakers and headphones.

Resources & Events

The TC on Loudspeakers and Headphones helps to maintain a Topic Website on Loudspeakers and Headphones.

Areas of Concentration

  • Transducer Design
  • Electronic Processing Techniques
  • Distortion Analysis
  • Measurement Techniques
  • Specifications
  • Digital speakers

Current Areas Of Work

  • Specifications Discussion:
  • Exploring terms, methods & definitions of power ratings. - a big topic

Recent/Planned Activities

  • AES 141st Los Angeles, 30/Sep/16 11:00 am
  • Chair: Steve Hutt
  • Vice-Chair: Juha Backman
  • Agenda:
  • Mission of the Loudspeaker and Headphone Technical Committee.
  • The committee works to ensure that the AES membership has the opportunity to learn of relevant new transducer technology as it develops, with an emphasis on sound field generation from loudspeakers and headphones.
  • Introduction:
  • Trends: - Comments welcome:
  • Micro speakers
  • Headphones
  • New Motor topologies
  • Other ?
  • Conferences:
  • Report on the 2016 AES International Conference on Headphone Technology
  • Chairs: Dr. Sean Olive & Patrick Hegarty
  • Standards:
  • Discussion of pertinent standards.
  • EIA 60268-5 update (W. Klippel)
  • End-of-Line Transducer testing - TCLH can do some ground work in conjunction with SC04-03 reviewing potential for standards or an Information Document.
  • Workshop Concepts:
  • Time domain measurement and analysis. Hans van Maanen has volunteered to chair. will organize for AES 142nd, Berlin
  • Power Capacity of Loudspeakers (drivers & systems) is a complex topic. A first workshop might only explore questions.
  • How can the AES2-2012 loudspeaker driver test be better explained in the industry. i.e. why is this test not relevant to loudspeaker systems?
  • What kind of power capacity information is important to system designers and users.
  • Can programme material be organized into some kind of definitions?
  • Etc. etc.
  • New Topics:
  • Chris Struck introduced the topic of “Measurement Uncertainty”
  • IEC boilerplate has a very general description about measurement uncertainty. Chris is working on expanding it. ISO 98 guide.
  • Next Meeting:
  • AES 142nd, Berlin 20-23/May/2017
