Soundscape: Paranal UT ambient sound

(Interior) This is the sound that you would typically hear inside a Unitary Telescope (UT). In this file, the noisiest elements are the cooling liquid and gas pumps that support the proper functioning of the instruments. Instruments are less known than telescopes, but telescopes would be rather useless without them. Each UT has room for three different instruments, and each instrument can do a specific scientific study with the light the telescope gathers.
