A very simple and inexpensive means of arranging staging is to introduce
delays between left and right channels such that the sound appears to be
coming from a particular direction. This is much easier to accomplish with

I have heard of and known a few audiophiles that go to great lengths to have
sound reproduced as accurately as possible and spend enormous sums to
accomplish that.
The term that was most silly in my view was holography; but I understood what
was meant. The aforementioned audiophiles claim to

I suspect that was abandoned because it's almost impossible to do in practice.
In any case, it's not what you want to know for safety purposes. You want to
know what the current test tells you; is the material overly soft at 125 C.
The stringency, and the enforcement procedures, vary in the different Member

Most of the responses agree with my understanding.
I will add that my recollection of the origins of the test in 60950 was related
to electrical connections under compressive loading where the compression is
needed to establish and ensure an electrical connection. Some custom made
Hi,

directives is within the EU. Is there someplace where we can find enforcement
actions that have been taken against companies for placing products on the
market that don't fully meet the applicable Directives? I

Hi,
We're working with a client that supplies Oil Spill response equipment. We're
evaluating the pumps and systems to the Machinery Directive, among others.
