Subject: [AUDITORY] paper (re)quest: R.I.P. Hayman: Listening to Dreams: A project for Middle Ear Muscle Activity Audio Level Telemetry. From: "hans w. koch" <hans.w.koch@xxxxxxxx> Date: Sun, 26 Apr 2020 19:39:38 +0200dear colleagues, during a seminar a student mentioned a paper by the composer Richard = (R.I.P.) Hayman from 1976, cited in a book by ione =E2=80=9Clistening in = dreams=E2=80=9D. the papers title "Listening to Dreams: A project for Middle Ear Muscle = Activity Audio Level Telemetry=E2=80=9D and its topic, referenced in = iones book seem interesting, but i couldn=C2=B4t find any trace of that = paper. also i would be interested, if there has been further research in this = direction, as recommended by hayman, who run into technical limitations = in his time. as a reference i quote the relevant passage from iones book below. thanks for any pointers, even debunking the whole :-) best hans w. koch professor fuer sound kunsthochschule fuer medien koeln peter-welter-platz 2, 4. OG 50676 koeln hans.w.koch@xxxxxxxx from ione =E2=80=9Clistening in dreams=E2=80=9D p3-4: Does the eardrum respond to Dream Sounds, much as the eyes respond to = visual dream stimuli? In 1976, Composer and dream specialist R.I.P. = Hayman was a self-described =E2=80=9Cguinea pig=E2=80=9D in the studies = of sound perception in sleep done at New York=E2=80=99s Montefiore = Medical Center. These studies monitored the phenomenon called = MEMA(Middle Ear Muscle Activity), assessing the feedback response of the = nerve endings on the tympanic tensor muscles of the eardrum. These = nerve-endings control muscle tension in response to outside sounds. = During dreams these muscles twitch in response to dreamed sounds, much = as eyes move tracing the movement in our perceived dream events. Hayman describes the experience in his paper Listening to Dreams: A = project for Middle Ear Muscle Activity Audio Level Telemetry. Using a = system in which a pressure=E2=80=94strain gauge was embedded in a custom = plastic ear mold fitted next to the tympanic membrane, the movement of = the muscles was registered on a polygram, alongside REM and = brain=E2=80=94-wave readings from Electrodes. The MEMA was registered at = sub audio frequencies, which none=E2=80=94the-less exhibited = surprisingly dynamic variations. The subjectively estimated sounds were = loud-85 decibels and over. Hayman subsequently performed a preliminary experiment. The goal was to = make an audio=E2=80=94level recording of MEMA; and-during six hours of = sleep in an audio studio, an attempt was made to record sounds emanating from the eardrum. Though many sounds were recorded, the = results were blurred by the interference of the sounds of breathing and = circulatory systems. It was apparent that in order to get an accurate = result, direct access to the nerve endings would be reqitired, which = with our current technology, would be an invasive and dangerous process. = Hayman speculates that eventually technol- ogy will advance enough to = create a method of listening to dreams that is safe for the dreamer. =E2=80=9CA great new frontier could be opened, giving a wondrous wealth = of imagination to the waking world,=E2=80=9D he surmises.
