Loudness Calculation and Critical Bands

The Journal of the Acoustical Society of America, 1957
The formula St = Sm + F(ΣS − Sm) is a linear approximation expressing total loudness St in terms of the loudness of the loudest band Sm and the sum ΣS of the loudnesses of all other bands. It has been shown that this formula holds when steady noises having reasonably continuous spectra are analyzed in terms of octave bands.

Recent KKR Band Calculations

1972
Among the computational methods for energy band calculations the KKR method has obtained an important place. The transparent physical concept of scattering on which this method is based has two immediate advantages. 1) In angular momentum representation the lattice geometry and the potential of the ions are separated, thus structure constants which are

Methods of calculation of band structures

1991
Abstract In parallel with the development of modern computers in the last twenty or thirty years, several methods for the calculation of the energy eigenvalues E(k) in crystals have been perfected, and computer programs now exist which make the calculation of band structures a fairly routine matter. Some results of such calculations have

LCAO Methods for Band Structure Calculations of Polymers

1978
The electronic structure of polymers has become in the last years a subject of great interest. Polymers as constituents of plastics are important from the point of view of structural materials; biopolymers play a fundamental role in life process and molecular crystals built up from polymers like (SN)X or the TTF-TCNQ system exhibit special physical ...

Semiempirical Band-Structure Calculations

1988
Different semiempirical crystal-orbital (CO) methods have been used to calculate the energy-band structures of one-dimensional periodic chains with larger unit cells (such as periodic DNA or protein models, TCNQ and TTF stacks) or of two-dimensional periodic protein models. The π-electron structure of the different periodic DNA stacks and of the H-N-C =

Reduced-basis method for band structure calculations

Physical Review E, 2007
We describe the application of the reduced-basis method in rapid and accurate determination of band energies in band structure calculations. The method is well suited for problems requiring repetitive evaluations of the band energies, especially in the many-query limit.
