Stereophile headphone measurement article

[HiWire]

I quickly browsed through an article about headphone measurements in this month's Stereophile. It's worth a look.

I read it as well, pretty interesting article.

Anyone care to paraphrase for those of us with no stereophile access;)?

Essentially the author goes over some of the challenges that you face measuring headphones (specifically the FR). He talks about getting accurate readings from the headphones on a dummy head and how headphone position alters the measurement from one reading to another.

Then he goes on to talk about the various ways you can go about applying corrections to the measured curves based on Free field or diffuse field response. He talks about the work of Thiele and how the headphone industry doesn't seem to have a consensus about which is better, FF or DF.

Then there's a bit with a dog.

He then goes on to show the FF and DF corrections for 4 headphones and how the graphs differ and so forth.

It's all very gripping. Truly neat read. It should show up on Stereophile website in a few months. It's in the August issue.

Fitz does his own headphone measurements

havin' some o' them old brain problems?

What else is new.

The other interesting thing in the article is the discussion on headphone output impedance. There seems to be a lot of variation...
