Re: maximal hearable speed of pulses
Title: Re: maximal hearable speed of
pulses
Hello Len:
It is a somewhat complicated
question that you are asking. If pulses are narrow enough, it is
likely that subjects can tell one pulse from a pulse pair with less
than a millisecond between the pulses in the pair - although it is by
no means clear that the listeners are actually resolving the pulses in
the pair. The subjects may well be perceiving one member of the
comparison (single vs dual pulses) as a "splat " sound and
the other as a"split" sound.
When it comes to individuating closely-spaced clicks or pulses, 10-12
clicks/sec is perhaps close to the upper limit. At higher pulse
rates, a train of pulses tends to be perceived as a single "buzz,"
with the individual elements not easily resolved or countable or even
accurately localized.

I hope that this helps. All kind wishes,

Hello everyone,
I am looking for any results on experiments that give a minimal time
between events so that the human ear can still hear two sperate
events.
At an interval of 50ms, people hear a tone instead of sperate beats,
maybe that is common knowledge but I would like to read a bit more on
the subject.
People seem to be very interested in investigating the frequencies we
can hear, and I can find many articles dealing with this subject, but
I would like to know more about the hearable speed of pulses, e.g.
when does fast tapping on a snaredrum become a drumroll...
Does anyone know any articles on this matter or is maybe currently
involved in any research around the subject?
Thanks in advance,
-Len
