<p>Method and apparatus for the conversion of sound waves to electromagnetic wave forms, preferably light, whereby sound waves are converted to an electrical signal and processed by a number of filters, the distribution between the filters being a result of the frequency of the sound wave and in which the filters are subsequently connected to their respective colour display and where the individual colour display's activation is directly proportional to their filter's amount of signal processing and where the colour display visualisation in a colour display means is in the form of a single colour or a mixture of two or more colour displays.</p> |
