background and aim: it has been several decades since the technology of frequency lowering (fl) has been proposed. however, primary research has revealed no benefits regarding the use of this technique. currently, new methods for fl and improvement of perception of speech and fricative sounds have led to the application of these methods by numerous companies to produce hearing aids. in this stu...

Conventional Flux Compression Generators (FCG's) are used to generate high power DC pulses. A new kind of (FCG's) with series capacitance called Capacitive Flux Compression Generator (CFCG) will be introduced and explained in this paper. This new kind is used to generate modulated high power pulses. There are some problems to establish a capacitance in high power and high frequency applications...

High gradients require high peak powers. One possible way to generate high peak powers is to generate a relatively long pulse at a relatively low power and compress it into a shorter pulse with higher peak power. It is possible to compress before DC to RF conversion as is done for the relativistic klystron or after DC to RF conversion as is done with SLED. In this note only radio frequency puls...

BACKGROUND frequency compression. AIM to evaluate the index of speech recognition (IPRF) using frequency compression in three different ratios. METHODS monosyllabic words were recorded using an algorithm of frequency compression in three ratios: 1:1, 2:1, 3:1, generating three lists of words. Eighteen listeners accomplished the IPRF using the modified words. They were subdivided in two grou...

OBJECTIVE The objective was to assess the degradation of speech sound quality produced by frequency compression for listeners with extensive high-frequency dead regions (DRs). DESIGN Quality ratings were obtained using values of the starting frequency (Sf) of the frequency compression both below and above the estimated edge frequency, fe, of each DR. Thus, the value of Sf often fell below the...

We investigate the frequency sensitivity of the human visual system, which reacts differently at different frequencies in video coding. Based on this observation, we used different quantization steps for different frequency components in order to explore the possibility of improving coding efficiency while maintaining perceptual video quality. In other words, small quantization steps were used ...

This paper describes the patient-specific frequency compression newly introduced in the Siemens micon platform. This feature is unique in its aim of ensuring benefit for all patients. The candidacy procedure of micon frequency compression indicates who is most likely to benefit from it and its fitting strategy prescribes the optimal parameters for these patients. Micon Frequency Compression 1 C...
