Multiple Comparison Tests01:13

Multiple Comparison Tests

4.5K
Multiple comparison test, abbreviated as MCT, is a post hoc analysis generally performed after comparing multiple samples with one or more tests. An MCT will help identify a significantly different sample among multiple samples or a factor among multiple factors.
It would be easy to compare two samples using a significance alpha level of 0.05. In other words, there is only one sample pair to be compared. However, it would be difficult to identify a significantly different sample if the number...

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.

Glassware Calibration

1.5K
Accurate calibration of glassware, such as volumetric flasks, pipettes, and burettes, is essential to ensure accurate measurements in the analytical laboratory. Calibration helps maintain consistency across measurements and prevents errors arising from inaccurate volumes.
Volumetric flasks: Volumetric flasks are designed to prepare aqueous solutions of precise volumes accurately with a calibration line on the neck. To calibrate a volumetric flask, it is important to fill it with distilled...

Introduction to Biological Bases of Psychology

4.7K
Biopsychology serves as a vital bridge connecting the intricate domains of biology and psychology, shedding light on how biological systems influence psychological phenomena. This field scrutinizes the biological substrates of behavior and mental processes, emphasizing the nervous system along with the roles of neurotransmitters, hormones, and genetics. It also incorporates evolutionary perspectives to explain the adaptive nature of mental functions.
The nervous system, the cornerstone of...

The Sense of Self: Reflected Self-Appraisal and Social Comparison02:57

The Sense of Self: Reflected Self-Appraisal and Social Comparison

56.2K
According to Charles Cooley, we base our image on what we think other people see (Cooley 1902). We imagine how we must appear to others, then react to this speculation. We don certain clothes, prepare our hair in a particular manner, wear makeup, use cologne, and the like—all with the notion that our presentation of ourselves is going to affect how others perceive us. We expect a certain reaction, and, if lucky, we get the one we desire and feel good about it. But more than that, Cooley...

Area of Science:

  • Audiology
  • Mobile Health (mHealth)
  • Biomedical Engineering

Background:

  • Pure-tone audiometry is the standard for hearing screening.
  • Mobile devices can be calibrated for hearing tests using reference sound levels.
  • Manufacturer-provided headphones allow for model-specific reference sound level calculations.

Purpose of the Study:

  • To compare hearing thresholds measured by a calibrated mobile device with pure-tone audiometry.
  • To evaluate the accuracy of mobile device-based hearing tests.

Main Methods:

  • Recruited 70 Otolaryngology Clinic patients with Android devices and bundled headphones.
  • Used the 'Hearing Test' app with model-specific reference sound levels for mobile measurements.
  • Conducted audiologist-assisted self-measurements in a sound booth (250 Hz to 8 kHz).

Main Results:

  • Mobile device hearing thresholds differed significantly from pure-tone audiometry (mean difference 2.6 dB).
  • 89% of mobile-based results were within 10 dB of pure-tone audiometry.
  • Sensitivity was 98% and specificity was 79% for the mobile screening method.

Conclusions:

  • Mobile device hearing self-tests with bundled headphones are highly compatible with pure-tone audiometry.
  • This method shows potential for large-scale hearing monitoring, screening, and epidemiological studies.
