It is estimated that some 37 million Americans suffer from allergic rhinitis and sinusitis each year. Many do not seek treatment; most find relief through prescription and over-the-counter medications. A minority of this population comes to the conclusion that medication is not a solution and seeks relief through endoscopic surgery. But the relief from sinusitis may have a cost – the quality of the voice.
A great voice has great resonance, affected by the body’s supraglottic area, pharynx, oral cavity, nasal cavity and paranasal sinuses. When minor alterations occur in the configuration of these anatomical structures, the result could be substantial differences in vocal quality.
Although the role of the nasal cavity and paranasal sinuses in vocal quality remains uncertain, disorders of nasal resonance may be described in two categories: excessive nasality and insufficient nasality. Anecdotally, patients who have undergone surgery for chronic sinusitis commonly note a change in their speech quality. However, a comprehensive review of the medical, speech, and acoustic literature failed to identify any studies addressing the effects of sinus surgery on speech.

Physicists have developed a new technique that uses electrical voltages to control the electron spin on a chip. The newly-developed method provides protection from spin decay, meaning that the contained information can be maintained and transmitted over comparatively large distances, as has been demonstrated by a team from the University of Basel’s Department of Physics and the Swiss Nanoscience Institute. The results have been published in Physical Review X.
For several years, researchers have been trying to use the spin of an electron to store and transmit information. The spin of each electron is always coupled...
What is the mass of a proton? Scientists from Germany and Japan successfully did an important step towards the most exact knowledge of this fundamental constant. By means of precision measurements on a single proton, they could improve the precision by a factor of three and also correct the existing value.
To determine the mass of a single proton still more accurate – a group of physicists led by Klaus Blaum and Sven Sturm of the Max Planck Institute for Nuclear...
