Sound Vibration

AbstractWhen a stereophonic track is heard through headphones or over loudspeakers, the image of a virtual performance is created in the mind. This virtual performance, which exists exclusively on the record, can be conceptualised in terms of the ‘sound-box’ (Moore 1993), a four-dimensional virtual space within which sounds can be located through: lateral placement within the stereo field; foreground and background placement due to volume and distortion; height according to sound vibration frequency; and time. From the mid-1960s, the increasing shift from mono to stereo meant that producers and engineers had to contend with the notion and potential of a song's sonic arrangement or mix, resulting in a disparity of sonic placement and a diverse range of sound-box configurations. By 1972, a normative positioning of sound sources within the sound-box was established, which we term the ‘diagonal mix’. This article focuses on the consolidation of this norm by means of a ‘taxonomy of mixes’ and the utilisation of visual representations which detail the sound-box configurations of a variety of pop/rock, easy listening and psychedelic tracks from 1966 to 1972.

Sound Vibration

Dental deficiencies coexist with hearing loss, and dental treatment can improve hearing acuity. To prove that different dentition affects the transmission of acoustic vibrations through bone conduction, we prepared six dry human skulls to reconstruct teeth and soft tissues. We measured the transmission of vibrations from the maxilla to the cochlea, in the toothless jaw (TJ), jaw with lateral defects with frame dentures (FD), toothless jaw with complete dentures (CD), and jaw with reconstructed dentition (RD). Each skull was flexibly suspended. The maxilla was stimulated with the bone vibrator Radioear B71. The vibrations of the pyramid were measured perpendicularly using the Polytec PSV-400-M2 scanning vibrometer. Characteristics of frequencies differed simultaneously on the left (l) and right (r) side of each skull. In all states (from 234 Hz to 5 kHz), we identified 10–21 resonant (R) and 9–21 antiresonant (AR) frequencies unilaterally (+/− 5%). In about 30% of cases, they were each time inconsistent with the “physiological” state-RD. In the 500 Hz–2 kHz frequency range (necessary for understanding speech), the effective vibrations velocities vRMS (mm/s) near cochlea were significantly lower in RD than in tree states, where (depending on the dentures) the least energy reached cochlea in FD and the most in TJ.
