| 描述： | Experimental sound that arose from a forum discussion. The sound consists of fast changing single tones with random frequency in the range 200Hz to 2kHz. At the start of the sound the tone changes every 20ms. The tones become progressively shorter (in continuous fashion) at a rate of 1ms every second, ie 20ms at t0, 19ms at t1s, 18ms at t2s etc. This was intended to be a crude test of perception of temporal resolution at some point we expected the discrete 'bleepy' tones to decay in to mushy noise which they kind of do near the end. Reading around the web it seems that temporal resolution perception is an ongoing (and complex) area of research. This test probably doesn't add much to the sum of human knowledge. But it's fun And possibly useful for teaching or research. |
