Dear List,
Just a question for those of you with experience using
ear probe microphones, do you ever hear the heartbeat? Iâve built a couple
of in-ear microphones, and can hear my own heartbeat, but the quality is
relatively poor, and only works in very low-noise conditions. I was looking
in to using dedicated probe mics, such as Etymotic ER-7C (http://www.etymotic.com/pro/er7c-ts.aspx) and whether that
might give me a better signal-to-noise ratio, but just wondered if anyone
has any experience of this before I buy some.
Thanks
Sam Jelfs
