drum membrane

Below, a number of drum membrane vibration modes are shown.

This relationship means that certain key features can be observed in both drum membrane modes and atomic orbitals.

With the tonoscope, quartz sand is spread onto a black drum membrane which is 60 cm in diameter.

The drum membrane acts as the soundboard for one or two strings strung from the end of the pole to the end of the drum.

Ghumat is a percussion instrument of earthen vessel having both sides open; on the bigger opening a leather (drum membrane) of monitor lizard is mounted.

None of the other sets of modes in a drum membrane have a central antinode, and in all of them the center of the drum does not move.

The drumheads are small, about 10 microns to 50 microns in diameter, with a gap between the drum membrane and the silicon substrate of only a few hundred nanometers.

A ring or some other accoutrement, probably symbolizing a frog, was during rituals moved around on the drum membrane, which contained some hundreds of runes (elks, sun, thunder, etc.).

Julius O. Smith III and others generalized the algorithm to digital waveguide synthesis, which could also be used to model acoustic waves in tubes and on drum membranes.

He therefore decided to operate on the left ear instead of the right, performing an ossiculectomy, removing a part of the drum membrane and scraping away the diseased portion of the inner ear.

Acoustic resonance is an important consideration for instrument builders, as most acoustic instruments use resonators, such as the strings and body of a violin, the length of tube in a flute, and the shape of a drum membrane.

For example, in all of the modes analogous to s orbitals (the top row in the animated illustration below), it can be seen that the very center of the drum membrane vibrates most strongly, corresponding to the antinode in all s orbitals in an atom.

To see the analogy, the mean vibrational displacement of each bit of drum membrane from the equilibrium point over many cycles (a measure of average drum membrane velocity and momentum at that point) must be considered relative to that point's distance from the center of the drum head.
