HUG - here for all audio enthusiasts

Since its inception ten years ago, the Harbeth User Group's ambition has been to create a lasting knowledge archive. Knowledge is based on facts and observations. Knowledge is timeless. Knowledge is human independent and replicatable. However, we live in new world where thanks to social media, 'facts' have become flexible and personal. HUG operates in that real world.

HUG has two approaches to contributor's Posts. If you have, like us, a scientific mind and are curious about how the ear works, how it can lead us to make the right - and wrong - decisions, and about the technical ins and outs of audio equipment, how it's designed and what choices the designer makes, then the factual area of HUG is for you. The objective methods of comparing audio equipment under controlled conditions has been thoroughly examined here on HUG and elsewhere and can be easily understood and tried with negligible technical knowledge.

Alternatively, if you just like chatting about audio and subjectivity rules for you, then the Subjective Soundings sub-forum is you. If upon examination we think that Posts are better suited to one sub-forum than than the other, they will be redirected during Moderation, which is applied throughout the site.

Questions and Posts about, for example, 'does amplifier A sounds better than amplifier B' or 'which speaker stands or cables are best' are suitable for the Subjective Soundings area.

The Moderators' decision is final in all matters regarding what appears here. That said, very few Posts are rejected. HUG Moderation individually spell and layout checks Posts for clarity but due to the workload, Posts in the Subjective Soundings area, from Oct. 2016 will not be. We regret that but we are unable to accept Posts that present what we consider to be free advertising for products that Harbeth does not make.

That's it! Enjoy!

  • Acoustics & measurement - training course, Oct. 09

    To keep up with the latest thinking and to be assured that the measurement techniques I use are compatible with industry best-practice (and to meet others doing speaker design/measurements) I am attending a two day course in New York next month. Just one part of the course is this:

    ================================================== ==================

    In our upcoming October seminar, the topic of Simulated Free Field Measurements is addressed. Alternative techniques, trade-offs and limitations, and methods for combining these techniques are demonstrated. Some additional details can be found in the attachment.

    Loudspeaker Performance: Measurements, Analysis & Diagnostics

    This two-day course focuses on loudspeaker testing. The fundamentals of acoustics and electro-acoustic measurements are presented, including instrumentation, data interpretation and information on how to perform appropriate tests. Advanced techniques for diagnosing problems in design and QC are shown. Practical demonstrations are provided throughout the course. This course is intended for technical persons who are responsible for the electro-acoustical performance of drivers and loudspeaker systems in R&D, Q.C/Q.A. or in production. The level and content are appropriate for both, novices and persons with test and measurement experience. This training will enable you to perform accurate loudspeaker measurements and provide you with the necessary tools to understand and correctly interpret the results.

    13-14 October 2009
    The classroom opens at 8:00 am. The class begins promptly at 8:30 am and runs until 5:00 pm with a one-hour break for lunch at 12:00 noon.

    I think that if nothing else, discussing the correlation between anechoic (free-field) measurements and in-room measurements, and contributing my own experiences over the years will be time well invested. That should put us in a strong position to discuss how to get the very best sound in your room.
