Spectrogram of a computer modem
With the aid of a coil pickup microphone it is possible to hear what seems to be an entire orchestra residing inside electrical appliances, each object emitting tones and pulses in contrasting frequencies and time signatures.
At first listen you might only hear dystopian chaos however a careful ear will begin to pick out the layers of sound which constitute the whole. Identifying the auditory structures of the inanimate objects that surround us is a rewarding process, the concentrated listening that is involved in the process connecting us to place in a unique way.
This particular recording is of a computer modem. Here the coil pickup microphone reveals the complexity of the digital signals that pass through our modern day offices as we sit dreaming of the weekend.
