Harmonic Frequency Lowering
A novel algorithm for frequency lowering in music was developed and experimentally tested in hearing-impaired listeners. Harmonic frequency lowering (HFL) combines frequency transposition and frequency compression to preserve the harmonic content of music stimuli. Listeners were asked to make judgments regarding detail and sound quality in music stimuli. Stimuli were presented under different s...
متن کاملfrequency lowering
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...
متن کاملOticon Frequency Lowering
Frequency lowering is a well-known technology in hearing aids that shifts high-frequency sound to lower spectral regions. Research and clinical findings have revealed the challenges of developing a strategy that can provide access to high-frequency speech without introducing unacceptable amounts of low-frequency distortion. Oticon Speech Rescue, the latest frequency lowering processor on the ma...
متن کاملFrequency-Domain Harmonic Analysis Methods
There are a large number of frequency-domain analysis methods that are in widespread use. The most popular of these are frequency scans, harmonic penetration, and harmonic power flow. Each of these techniques can be employed on a “per-phase” (positive or zero sequence) or “multi-phase” basis and each technique utilizes an admittance matrix system model developed from individual component-level ...
متن کاملModified Verification Approaches for Frequency Lowering Devices
Providing effective hearing aid fittings for high-frequency hearing loss is a challenging and important clinical task. The importance of this task becomes even more apparent when considering the development of speech and language skills in the hearing-impaired pediatric population. Current research suggests that children require audibility of a broad bandwidth of speech for optimal access to hi...
