The soundscape, chapter 1: Insects

April 5th, 2013

Here I come with a first entry about the newly created category The soundscape (Schafer);

About insects.

»The most easily recognized insect sounds for modern man are the most irritating. The mosquito, the fly and the wasp are easily distinguishable. The attentive listener can even tell the difference between male and female mosquitoes, the male usually sounding at a higher pitch. But only a specialist, such as a beekeeper, knows how to distinguish all the variants of the bee sound. Leo Tolstoy kept bees on his estate, and their sound is described in both Anna Karenina and War and Peace. “His ears were filled with the incessant hum in various notes, now the busy hum of the working bee flying quickly off, then the blaring of the lazy drone, and the excited buzz of the bees on guard protecting their property from the enemy and preparing to sting.” When a queenless hive is dying, the beekeeper knows this too from the sound.

»The sounds of insects are produced in a surprising number of ways. Some, such as those of the mosquito and the drone bee, result from wing vibrations alone. The general range of wing frequencies in insects is between 4 and upward of 1,100 beats per second, and much of the pitched sound we hear from insects is produced by these oscillations. But when the butterfly moves its wings at between 5 and 10 times per second, the result is too faint and too low to be registered. In the honeybee, the wing beat frequency is 200 to 250 cycles per second and thc mosquito has been measured at up to 587 cycles per second. These frequencies would thus be the fundamentals of the resulting sounds, but as a rich spectrum of harmonics is also often present, the result may be a blurred noise with little discernible sensation of pitch.

»Among the loudest of insects are the cicadas. They produce sound by means of ridged membranes or tymbals of parchment-like texture, close to the junction of the thorax and  abdomen, which are set in motion by a powerful muscle attached to the inner surface; this mechanism produces a series of clicks in the same manner as does a tin lid when pressed in by the finger.  The movement of the tymbals (amounting to a frequency of about 4,500 c.p.s.) is greatly amplified by the air chamber that makes up the bulk of the abdomen, so that the sound has been heard as far as half  a mile away.

»Difficulties have been encountered in the analysis of the precise intensities and frequencies of insect sounds. This is because individual specimens are hard to isolate for recording purposes and also because the sounds insects make are generally complex frequency structures or broadband noises, with harmonics often rising into the ultrasonic range. The locust Schisfocera gregaria emits a sound of about 25 decibels when recorded very near the source, but the wing beat noise rises to 50 decibels when in flight. The flight noise of the desert locust has been measured as high as 67 decibels at a distance of 10 centimeters from the microphone. The sound output of many moths may be as little as 20 decibels quite near the source while insects with hard wings and bodies, such as flies, bees and beetles, produce sounds up to 50 or 60 decibels. Since the human ear is more sensitive to sounds in the middle and upper frequency areas, insect sounds in the upper range (an average might be 400 to 1,000 c.p.s.) sound louder to the ear but no human ear can hear the higher frequencies of the locust’ s call, which have been found to contain frequencies of 90,000 c.p.s., thats is about two octaves higher than human ear can detect.

»Many insect sounds are pulse modulated or varied in other subtle ways, but despite the “grainy” effect such modulations create, the impression with many insects is of a continuous, unvarying monotony. Like the straight line in space, the flat line in sound rarely occurs in nature, and we will not encounter it again until the Industrial Revolution introduces the modern engine.

 

Having read that, specially about cicada, I’ll forward you to a recording I made in Cambodia, north of Khmer temples, Kulen Mountain, where a really psichedelic sound scared me in the middle of the jungle. I asked a local guy about it, after recording.
He said something like ‘sikada’, and that I wrote on my notebook.

The most fantastic insect I’ve ever heard

Apuntes de electrónica

[Los posts de ésta categoria están ordenados cronológicamente ascendentes]

Recuerdo cómo sobre el año 2000 colaboraba y escribía en el foro de clubbingspain.com y relataba al detalle todas mis experiencias de club y underground allá donde iba. Festivales, eventos, sellos. La música y su estrecha relación con la política, y las drogas, por ejemplo. Por aquel entonces mi admiración por esta música y los artistas relacionados estaba en su auge, y hablaba sin pudor de mis sentimientos, lo que veía y lo que hacía la gente. Eran leídos…

Entre los años 2004 y 2006 escribí un blog (éste era en papel, personal, como antiguamente) sobre esta música y esas conexiones, de manera algo íntima.
Acabo de encontrarlo. Escribía con pluma y ganas, y ha sido muy interesante descubrirlo.

Muchos devaneos mentales están extraidos del famoso libro ‘Loops’ que fue fuente de inspiración, sobre la que yo añadía mis ideales.

Aunque la edad me ha separado en alguna medida del ámbito y de algunos razonamientos juveniles, he decidido publicarlos y añadir una categoría (en español) sobre la que ir haciendo entradas desde estos apuntes:
Apuntes de electrónica
Para leer sólo acerca de ellos cronológicamente podéis clicar en ella.

También podéis ver el cuaderno digitalizado aquí.

Es curioso que muchas veces hablo de la música electrónica como la música del futuro.
Y sin embargo el cuaderno comienza así:

Electronic music notes, start

Hablo del año 0 de Ella (por cierto, cuando escribo Ella, en todo el cuaderno, me refiero a la musica electrónica) como la invención de los intonarumori de Russolo, 1910. Y que Ella no está inventada aún, Ella es la música del presente. Mola, porque con eso digo que el futuro es ésto que vemos, nuestro presente, y así me acerco más a ese futuro de ciencia ficción que tanto me mola soñar.

 

The soundscape (Schafer)

April 1st, 2013

There’s this book from Murray Schafer, ‘The soundscape’.

Murray (born 18 July 1933) is a Canadian composer, writer, music educator and environmentalist perhaps best known for his World Soundscape Project, concern for acoustic ecology, and his book The Tuning of the World (1977), of which I’ll talk now.

The book talks about our sonic environment, the ever-present array of noises with which we all live. Beginning with the primordial sounds of nature, we have experienced an ever-increasing complexity of our sonic surroundings. As civilization develops, new noises rise up around us: from the creaking wheel, the clang of the blacksmith’s hammer, and the distant chugging of steam trains to the “sound imperialism” of airports, city streets, and factories. The author contends that we now suffer from an overabundance of acoustic information and a proportionate diminishing of our ability to hear the nuances and subtleties of sound. Our task, he maintains, is to listen, analyze, and make distinctions.

Though sometimes a little hard to read for me in the morning, while travelling to office, the book has no waste. I’ve coined some of the most interesting pages and will share them here from now on under the category ‘The soundscape (Schafer)‘ (in english).

I hope you enjoy with those, I did.

Secret sound agent 007

Sometimes when you hold a shotgun microphone you feel like a secret agent with a gun… waiting for the perfect sound to happen and shoot at it.

These are a few funny pics representing this feeling:

Shut up Speak now. I’m gonna kill record you.

And then I also made a story about a cop and a contrabass. haha

Our story in two minutes

How about this student who made his final project for high school creating this video with our history compressed within 2 minutes of stunning images?
Remarkable.
