Size Effect in Heterogeneous Nucleation
Assuming a spherical nucleating particle, the effect of particle size and surface properties upon nucleation efficiency is investigated. A general result is derived which is then applied to theExpand

Nonlinear generation of missing modes on a vibrating string
The nonlinear transfer of energy among modes of different frequencies on a vibrating string is investigated both theoretically and experimentally. The nonlinearity is associated with the well‐knownExpand

Autonomous vibration of simple pressure‐controlled valves in gas flows
Pressure‐controlled gas‐flow valves are responsible for sound generation in woodwind and brass instruments, and in the vocalization of many animals. When only a single degree of freedom is allowedExpand

Bird song—A quantitative acoustic model
A detailed quantitative physical model is developed which gives a successful quantitative account of the “voiced” song of birds such as ravens. Using available anatomical and physiological data, theExpand

The nonlinear physics of musical instruments
Musical instruments are often thought of as linear harmonic systems, and a first-order description of their operation can indeed be given on this basis, once we recognise a few inharmonic exceptionsExpand

Songbirds tune their vocal tract to the fundamental frequency of their song.
In human speech, the sound generated by the larynx is modified by articulatory movements of the upper vocal tract, which acts as a variable resonant filter concentrating energy near particularExpand

Acoustics of the avian vocal tract
The general principles underlying the acoustic performance of the avian vocal tract are examined both theoretically and experimentally. The formantresonances produced both by the total vocal tractExpand
