Hearing

Hearing

When we hear a sound, our nervous system is detecting sound waves—pressure waves of mechanical energy traveling through a medium. The frequency of the wave is perceived as pitch, while the amplitude is perceived as loudness.

Fast Fourier Transform

Fast Fourier Transform

The Fast Fourier Transform (FFT) is a computational algorithm designed to compute the Discrete Fourier Transform (DFT) efficiently. By breaking down the calculations into smaller, manageable sections, the FFT significantly reduces the computational complexity involved. Direct computation of an N-point DFT requires N2 complex multiplications, whereas the FFT algorithm needs only (N/2)log⁡2N multiplications, offering a much faster performance.
The computational efficiency of the FFT becomes...

Fast Decoupled and DC Powerflow

Fast Decoupled and DC Powerflow

The fast decoupled power flow method addresses contingencies in power system operations, such as generator outages or transmission line failures. This method provides quick power flow solutions, essential for real-time system adjustments. Fast decoupled power flow algorithms simplify the Jacobian matrix by neglecting certain elements, leading to two sets of decoupled equations:

Gene Evolution - Fast or Slow?

Gene Evolution - Fast or Slow?

The genomes of eukaryotes are punctuated by long stretches of sequence which do not code for proteins or RNAs. Although some of these regions do contain crucial regulatory sequences, the vast majority of this DNA serves no known function. Typically, these regions of the genome are the ones in which the fastest change, in evolutionary terms, is observed, because there is typically little to no selection pressure acting on these regions to preserve their sequences.
In contrast, regions which code...

Metabolic States of the Body: Fasting and Starvation

Metabolic States of the Body: Fasting and Starvation

During the initial hours of fasting, the body uses up its glycogen stores as an energy source. Once these glycogen reserves are depleted, the body begins breaking down stored triglycerides and structural proteins. During this stage, glycerol becomes a key substrate for gluconeogenesis, while free fatty acids undergo beta-oxidation to provide energy for tissues, such as skeletal muscle. In the fasting state, the body spares protein breakdown as much as possible to conserve muscle and structural...

Area of Science:

Audiology
Biomedical Engineering
Digital Health

Background:

Hearing loss is irreversible, necessitating hearing aids or cochlear implants.
Conventional hearing tests are time-consuming and costly, requiring audiologist supervision.
There is a need for accessible, patient-friendly hearing assessment solutions.

Purpose of the Study:

To develop and validate a smartphone-based audiometry method for hearing self-assessment.
To leverage existing hearing aids as audio output devices for a self-test.
To reduce the time and cost associated with traditional hearing evaluations.

Main Methods:

A smartphone-based hearing self-assessment (SHSA) system was developed, integrating hearing aids, a smartphone interface, and a novel "coarse-to-fine focus" algorithm.
Low-power wireless communication controlled hearing aid audio stimulus generation.
Objective sound level precision and subjective accuracy tests were conducted.

Main Results:

Objective measurements demonstrated sound level precision within a 0.5 dB HL variation across six frequency bands.
Subjective tests with 20 participants showed an average difference of less than 6 dB HL compared to conventional tests.
The SHSA system achieved over 50% time savings on average for hearing tests.

Conclusions:

The proposed smartphone-based audiometry method offers a precise and efficient alternative for hearing self-assessment.
The SHSA system demonstrates potential to improve accessibility and reduce the burden of hearing testing for individuals with hearing loss.
This technology could empower patients with a convenient tool for monitoring their hearing health.
