Described by the music writer Robert Philip as "the first composer to take the gramophone seriously", he had already recorded much of his music by the early acoustic-recording process for His Master's Voice (HMV) from 1914 onwards, but the introduction of electrical microphones in 1925 transformed the gramophone from a novelty into a realistic medium for reproducing orchestral and choral music.
F. K". had been played on a bare stage without electrical lights or microphones and with the characters speaking in iambic pentameter, the effect of historical verisimilitude would have been considerably reduced.
The air-conditioned auditorium is equipped with individually-controlled microphones and electrical outlets at each seat to optimize audience participation, and possesses excellent acoustics.
The incoming sound wave, having been converted by a microphone into an electrical signal, produces a time-varying magnetic field in the gap of the magnet.
Determination of deformation of a microphone membrane under electrical loads (varying voltage) is of fundamental importance for the design and fabrication of a microphone.
Once the connection is made, the caller's voice is transformed to an electrical signal using a small microphone in the caller's handset.
Michael Gerdsman crochets electrical goods – mobiles, a hairdryer, microphones, and pot plants, while Raimundo Camilo obsessively draws over Brazilian banknotes with a ballpoint pen, encrusting them with whorls and faces and tiny patterns.
The acoustic transfer admittance of the coupler, including the thermal conductivity effect of the fluid, must be modelled precisely to obtain the accurate sensitivity of the microphones from the electrical transfer impedance measurement.
Frequency linearity is the ability of a microphone to yield an electrical output that is proportional to the amplitude of the sound input over the entire frequency range.
We propose a method of increasing the overall sensitivity of the microphone by increasing its electrical sensitivity.
