HEARING


Sound fills our environment and ceaselessly showers our brain. It speaks to us, informs us, and keeps us alert about everything around us. With sound we learn to communicate and to feel emotion. And to distinguish noise from silence.

 

 

What we know

We open our ears and the world penetrates, inevitably, in the form of sounds. A negative consequence of this is noise pollution, particularly serious in urban nuclei. So, a review of the noise situation in the European Union has been necessary and an analysis of the measures that need to be taken to reduce it.

Can you imagine the possibilities that open up when each colour can be converted into a specific sound?

IRIS Project

The website of the University Audiovisual Institute lets us see a particular project on creating an interface that enables blind people to explore a flat space with the hand and convert each colour into a particular sound. The authors of this project call it a perception metaphor.


Recently, many approaches have been tried with a view to overcoming the limitations of our senses. One of these involves constructing a sound landscape to correspond to a visual landscape in real time by means of a conversion algorithm. For example, the sounds at the top of the image are treble, those at the bottom, bass; and the bright points give a loud sound, the dark points a weaker one.

A camera for the blind

An invention of this type is presented at this site. Click on “Introduction” and then on the plan of the introduction page for access to a practical demonstration of the invention. The site is somewhat complex and slow, but is worth taking a look at.


What we are

Hearing is a complex system that captures vibrations from the exterior, takes them through the middle ear and transduces them in the inner ear. Analysis of the stimuli is carried out by the brain.

Histology of hearing

This site gives an interesting lesson in the anatomy of the ear: a schematic, clear, concise presentation which teaches us a little more about this complex organ.


Why can some people perceive and describe pure pitches while others can only describe a pitch as relatively higher or lower? If someone coughs during a concert, why do we not perceive it as part of the music? Why do we identify the solo violinist as differentiated from the orchestra? If each ear receives only a wave of variable width and frequency, how are we able to distinguish all these different aspects?

Auditory scenes

An attempt is made to answer these questions from the analysis of the so-called “auditory scenes”. At this educational site, aimed at people with some previous knowledge of the subject, you’ll find answers to some of these questions.


The sound waves of music, through the eardrum and middle ear, make the ciliary cells of the inner ear dance, which is converted into nerve impulses and the sensation of sound. We can imagine how depending on the music reaching us from outside, faster or slower, louder or softer, the ciliary cells will dance faster or slower, over a greater or lesser width, and how our perception is born from this dance.

The dances that let us listen

These pages offer a very instructive approach to a dance of this type.


What we create

Hearing is a window on the world. From it we can be carried where the melody wants. It leads us. Looking at a mountain, with its cartographic information, a melody may emerge. This is topophony.

Topophony: earth music

If you want to have a topophonic experience on this website, by clicking on the “web” button you can choose a point on the compass rose and obtain the image and melody associated with that point.


Music and words are perceived as sounds with which our brain elaborates emotional stimuli.

SOUNDSITE, an online journal of the theory, philosophy and art of sound

Take part in this journal that deals with the theory, philosophy and art of sound. A search engine is provided for finding related information. You’ll find sound clips, information on conferences and links to interesting sites.


Open your ears, get your sense of hearing online and visit this website, because the bits are also sounds and music.

MidiWorld

Here, if you look around the “MIDI files” section, you’ll find all kinds of melodies and sound sequences, both classical and modern, which you can download and use however you like.


Combining images and sounds in a new multimedia idea, evoking music and ambiences and relating them with pictures and sculptures. This is the aim of the participants in the exhibition “An art installation at the end of the century”.

Millenium Overdrive

Sound compositions take their inspiration from various sources such as jazz, classical music, industrial and avant-garde music, and are created electronically.


The creators of this website are fully aware that the Internet is communication and sharing, in this case, of our enthusiasm for and interest in one type of music, and have filled it with videos, sound files, interviews, song lyrics, and everything you can imagine.

Enya, an unofficial page

This is an excellent example of an unofficial page on a musician, created by fans away from the record companies and therefore extremely interesting.


The Internet is also music, and for lovers of good jazz this site is essential for flattering our sense of hearing.

Verve Interactive

As well as an interesting information point on artists and new releases from the major record company Verve, here you can enjoy sound files with selected excerpts from the best pieces, not forgetting the chat areas and competitions.


If what you enjoy is experimenting with musical instruments, don’t fail to visit this page, where you can turn the pointer of your mouse into a violin bow.

Pixound

Here you can get the Pixound plug-in you need to do so. When the plug-in is activated, you can have an enjoyable time playing with the colours and sounds, and making music (in tune!) just by moving the mouse. You end up confusing the senses of sight and sound.
