‎First appearance of a founding paper in musical theory and the physics of acoustics, in which the term ""acoustique"" is coined. The paper deals with the relations of the tones of the musical scale. It established the practice of music upon a science superior to it which Sauveur calls ""Acoustics"", the subject of which is sound in general. This is Sauveur's main paper on acoustics in which he states the first clear recognition of the composite nature of the vibration of strings.""Like Mersenne and others in the Seventeenth century, Sauveur used musical experience to obtain information on sound and vibration. According to Fontenelle, Sauveur was fascinated by music, even though he had no ear for it, and consulted frequently with musicians. Despite the musical foundation of his work, Sauveur proposed the development of a new subject, which he named ""acoustique"", dealing with sound in general rather than with the ""son agréable"" of music."" (DSB XII, p. 127).""Joseph Sauveur (1653-1716) introduces the term ""acoustics"" for the study of sound and examines the relations of the tones of the musical scale in the memoir ""Systeme général des intervalles...."" (General System of sound intervals and its application to all musical systems and instruments) - the paper offered - He shows that a string can vibrate at integral multiples of a a fundamental frequency simultaneously with vibrating at the fundamental frequency itself, callinf the toned produced by the vibrations at the multiples the ""harmonics"" of the fundamental tone.""(Parkinson ""Breakthroughs"" 1701 P.‎

‎First edition of Chladni’s landmark work on the production of sounds from solid bodies, inaugurating the field of acoustics. Here, he demonstrated the method by sprinkling sand on plates of glass or metal and drawing a bow down their sides to produce a visible vibration pattern called ""Chladni figures” or “Chladni patterns”. ""The production of sound from solid bodies was not clearly understood until Chladni devised the method of sand figures to illustrate the structure of vibrations in a solid body"" (Norman). Chladni ""was the first to reduce the general association between vibration and pitch to a tabular basis and thus to lay the foundation of the modern science of acoustics"" (PMM). In his famous 1787-experiment, Chladni drew a bow over a piece of centrally fixed metal plate covered with sand, and the vibration of the plate caused the sand to move and accumulate around the nodal lines where the surface remained still, forming Chladni figures. The experiments by Chladni are a corner stone of modern acoustics. However, the motion of particles before they settle to the nodal lines is still not very well understood, and only hypothetical models have been put forward. Chladni had visited the Paris Academy in 1808 and had demonstrated the vibration patterns before an audience that included not only the leading French scientists but Napoleon himself"" Napoleon set a prize for the best mathematical explanation but no satisfactory explanations came out of it. Napoleon famously remarked ""Chaldni mhas made sound visible"" (Dibner). Variations of this technique are still commonly used in the design and construction of acoustic instruments such as violins, guitars, and cellos. Since the 20th century, it has become more common to place a loudspeaker driven by an electronic signal generator over or under the plate to achieve a more accurate adjustable frequency. In quantum mechanics, Chladni figures (""nodal patterns"") are known to be related to the solutions of the Schrödinger equation for one-electron atoms, and the mathematics describing them was used by Erwin Schrödinger to arrive at the understanding of electron orbitals.Dibner 150PMM 233Norman 480Sparrow 39‎
