Sensorineural Hearing Loss for Low Tones
Archives of Otolaryngology - Head and Neck Surgery, 1967EXPERIENCE over the past ten years leads us to believe that lesions at the various levels of the auditory system are characterized by different patterns of response to a battery of auditory tests. In the evaluation of patients with known hearing disorders, such as acoustic trauma or verified acoustic neuroma, otologists and audiologists are able to ...

Low-loss dielectrics are important technologically as insulators but there is little understanding of the physical causes of this property and even their spectral response is not well documented—this study has revealed a number of different types of behaviour which do not appear to have been recognised previously. Most low-loss materials show a “flat”,

Low-loss terahertz ribbon waveguides
Applied Optics, 2005The submillimeter wave or terahertz (THz) band (1 mm-100 microm) is one of the last unexplored frontiers in the electromagnetic spectrum. A major stumbling block hampering instrument deployment in this frequency regime is the lack of a low-loss guiding structure equivalent to the optical fiber that is so prevalent at the visible wavelengths.

Low-loss photon-to-electron conversion
Optical Review, 2014Silicon photodiodes with induced junction structure can reach low-loss photon-to-electron conversion. The calculated conversion efficiency in the visible wavelength range typically deviates less than 10 ppm from unity and its uncertainty is about 100 ppm at room temperature or as low as 1 ppm at 78 K.

A Low-Loss Built-In Current Sensor
Journal of Electronic Testing, 1999This paper presents a novel built-in current sensor that uses two additional power supply voltages besides the system power supply voltage, and that is constructed by using a current mirror circuit to pick up an abnormal IDDQ. It is activated only by an abnormal quiescent power supply current and minimizes the voltage drop at the terminal of the ...

Low-loss silica-on-silicon waveguides
Optics Letters, 2011Waveguiding structures are one of the fundamental components of integrated photonic circuitry. Devices with low loss and a linear response across a wide wavelength range are especially desirable. In the present Letter, we have successfully developed and characterized low-loss silica waveguides integrated on a silicon substrate with a novel suspended ...

Development of low-loss sapphire mirrors
Applied Optics, 1997We report on the successful development of low-loss sapphire mirrors for use at a 1-mum wavelength. Methods for polishing and coating are described. The analysis of each process shows a roughness of better than 0.1 nm, a coating scattering of 1 ppm, and a surface scattering of 13 ppm.

Low-loss single polarization fibers
Applied Optics, 1983Low-loss single polarization fibers that maintain a state of linear polarization well are proposed. This fiber is composed of four regions: the concentric circular GeO2- and/or P2O5-doped core and pure silica clad regions for constructing the low-loss waveguide, and the B2O3-doped elliptical-jacket and the silica outer support regions for introducing ...

Low-loss semiconductor waveguide bends
Optics Letters, 1988An experimental comparison is made between the losses of waveguide bends in disorder-delineated waveguides in semiconductor superlattices composed of GaAs and AlAs layers for simple abrupt bends and abrupt bends with an additional half-angle guiding wall proposed by Shiina et al. [Opt. Lett. 11, 736 (1986)].
