Badak* and Ajay A.Gurjar* Department of Electronics and Telecommunication Sipna C.O.E.T amravati Amravati, India *Email: [email protected], [email protected] Abstract: In a day to day life we come across many sounds which are mechanical vibration that may be through air or water. To every sound some form of visual image is attached which is normally not visible. We are making an attempt to make sound visible. This paper gives a novel approach to convert one dimensional signal (sound) into two dimensional signals (Image) which can be used as a tool to freeze sound in the form of images. We are using low frequency signals as an example. But as the frequency increases the patterns become more complex. Keywords: particle contamination, CSM, analytical method. Chladni known as the father of Acoustics, who laid Introduction the foundation for the study of physics of sound. In 1831 the great experimental scientist In the beginning was the ‘word’ or in Sanskrit, .Michael Faraday, published a paper of describing ‘Nada Brahma’, the world is sound. The amazing his observation of geometric ‘nodal forms’. Appear power of sound to change and shape matter is in granular solid under the effect of vibration. fundamental to all life and many spiritual In 1885, an American, Margaret watts Hughes, a technologies. Cymatics is the study of wave singer and ‘devout Congregationalist’, begin phenomenon, which emerged as a distinct scientific experimenting with the ‘eidophone’,a small, discipline in the 1950s. Robert Hooke, Ernst chladni, saxophone-like instrument with a membrane spread Margaret watts Hughes and Hans jenny were the tightly over the bell upon which she spread various initiators of Cymatics each of whom found wonder powers and liquids by singing long, sustained tones in The changing patterns as they animated matter into this device, she was able to create finely reacting sound. We used 110 Hz to 523Hz audio detailed images mirroring the brachiated structure of signal for the experimentation which corresponds to plants and flowing water. A3 to C5 Musical Notes. As we gradually shift from Jumping ahead to the 1960s in the small town of low frequency to higher one the pattern corresponds Dornach in the foothills of the Swiss Alps.Dr Hans to it become more complex. As a unique pattern is Jenny constructed a similar device, which he called a obtain for each frequency it can be used in tonoscope, to transform the human voice into visual telecommunication as one of the coding techniques ‘sound figures’. He had developed a toy which was as that of PN sequences for secured communication. used to teach deaf children to speak. Further jenny Cymatics work on the principle of standing wave uses frequency generator and amplifier to get patterns and different patterns are developing different images Jenny coined the term ‘Cymatics’ because of number of nodes and antinodes develop (Kyamatics in German) from the Greek to kyma on the plate. (pertaining to waves) [6]. On July 8,1680, the English experimental Acoustic engineer and long-time UK Cymatics philosopher, Robert Hooke broke, broke the visible researcher, John Reid has developed an electro- sound barrier when he spread flour on a small glass acoustic device enabling one to visualize the voice, plate and passed a violin bow along the edge of the music and other sound sources Jeff Volk tells how plate different pattern are observed. Sound frequencies used in Cymatics can tone up our About 100 years later this phenomenon was re- body and tune up our mind, cyamatherapy which discovered by the German physicist, Ernst F.F uses specific sound frequencies to stimulate muscles, organ, even bones, to their natural state of resonance. 1004-1 World Acad. J. Eng. Sci. 01 1004 (2014) Badak and Gurjar Hypothesis: Relation between the type of board Experimental setup and the shape on the board According to (1), sounds that have same frequency have different velocities because of the bulk modulus of their media. If the A. Cymatic image develoment velocity varies, according to (2), Fig.1 Denote the functional blocks to generate The wave length would change. This change cymatic images. Musical tones A3 to C5 are having indicates that the distance between two consecutive a frequency range from 110Hz to 523 Hz and are nodes would differ according to its material. The mention in the table I are generated using a function lines are formed by particles on the node, so the generator and are applied to the audio amplifier. change of location of nodes would result in the Audio amplifier is used to develop the desired level change of the shape. of vibration on the plate. Speaker is connected to the audio amplifier and plate is attached properly to the Table I: Represents the results speaker so that maximum vibration should reach to Sound to image Sr.no the plate.

Hypothesis We are using two hypotheses about the change of shapes of Visualized sound [2]. 220 Velocity=Square root of (Bulk modulus/ Density) (1) Velocity= Wavelength * Frequency (2) 1004-2 World Acad. J. Eng. Sci. 01 1004 (2014) Badak and Gurjar Sound to image Sr.no Sound frequency (Hz) Corresponding Image Conclusions Form above results shown in table I it is clear 247 that corresponding image pattern’s complexity increases as the sound frequency increased. Cymatics can be used as a transformation tool to convert Single dimensional signal (sound) into two dimensional signals (Image). It provides new 262 dimension to analyses sound. It can be used to provide healing effect through visualization also visualization will lead people to appreciate auditory art such as music. 294 Acknowledgments I give my sincere thanks to Sipna College Of Engineering And Technology Amravati for providing the platform to work.
