The Journal of the Acoustical Society of America, 1963
A device is described for the measurement and automatic printout of the decay rate of reverberant sound energy or the damped vibration of structures. The design provides for a choice of decay ranges from 10 to 100 dB (in 10-dB steps), the point in the decay at which the timing starts (in 2-dB steps), and the number (up to 99) of decays to be measured ...

Rate of Decay of Auditory Sensation
The Journal of the Acoustical Society of America, 1964The rate of decay of auditory sensation was investigated by measuring the minimum silent interval that must be introduced between two noise pulses to be perceived. The value of this critical time Λt was determined for different intensity levels of both the first and the second pulse. It is shown that in this case the sensation level of the second pulse

Light hadronic decays and decay rates of quarkonia
AIP Conference Proceedings, 2011The Light hadronic decay and decay rates of mesons (QQ) are studied in the NRQCD formalism in terms of their short distance and long distance coefficients. The long distance coefficients are obtained through phenomenological potential model description of the mesons.

Annals of Physics, 1961
Abstract The total rate and the electron energy spectrum are calculated for the decay of a negative muon bound in an atomic 1s state, using relativistic electron and muon wave functions appropriate to an extended nuclear charge distribution, and using a general local, nonderivative, decay interaction.
