Summary
A smartphone hearing app accurately screens school-age children's hearing, matching traditional methods. This mobile approach shows promise for widespread hearing impairment detection in schools.
Area of Science:
- Audiology
- Public Health
- Mobile Health Technology
Background:
- Pure-tone screening (PTS) is the standard for school-age hearing assessments.
- Mobile devices offer potential for accessible audiometric testing.
Purpose of the Study:
- To introduce a novel smartphone application for rapid hearing status screening in children.
- To provide stratified hearing test values using a mobile-based approach.
Main Methods:
- A prospective cohort study involving 85 school-age children (170 ears).
- Comparison of a smartphone-based screening app with standard sound-treated booth PTS.
- PTS used 4 tones (500 Hz at 25 dB; 1000, 2000, 4000 Hz at 20 dB).
- Smartphone app utilized 20 stratified hearing scales; results compared to pure-tone average (PTA).
Main Results:
- Both methods yielded comparable pass/fail results (168 pass, 2 fail).
- The smartphone app accurately identified moderate or worse hearing loss (PTA > 25 dB).
- Sensitivity and specificity of the smartphone method were both 100%.
Conclusions:
- The smartphone-based self-hearing test demonstrated high agreement with conventional PTS.
- This mobile hearing screening method shows potential for use in school-aged populations.

In cross-sectional research, a researcher compares multiple segments of the population at the same time. If they were interested in people's dietary habits, the researcher might directly compare different groups of people by age. Instead of following a group of people for 20 years to see how their dietary habits changed from decade to decade, the researcher would study a group of 20-year-old individuals and compare them to a group of 30-year-old individuals and a group of 40-year-old...

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.

Profile leveling and cross-sections are surveying methods used to determine and document terrain elevations for infrastructure projects such as highways, railroads, canals, and pipelines. These methods provide data for earthwork planning and alignment of proposed routes. Profile leveling involves measuring elevations along a fixed line to create a vertical terrain profile. A surveyor sets up a leveling instrument at the benchmark (BM) and records a backsight (BS) to determine the...

4.5K
The cross-sectional anatomy of the spinal cord offers a detailed view of its complex structure and function within the central nervous system. At the core of the spinal cord lies the gray matter, characterized by its butterfly or "H"-shaped appearance in cross-section. This central region is enveloped by white matter, with the overall structure divided into symmetrical halves by the dorsal median sulcus and the ventral median fissure.

Unlike mitosis, meiosis aims for genetic diversity in its creation of haploid gametes. Dividing germ cells first begin this process in prophase I, where each chromosome—replicated in S phase—is now composed of two sister chromatids (identical copies) joined centrally.
The homologous pairs of sister chromosomes—one from the maternal and one from the paternal genome—then begin to align alongside each other lengthwise, matching corresponding DNA positions in a process...

2.7K
This lesson deals with the crossed aldol reaction using weak bases. The self-condensation of an aldehyde having α hydrogen is prevented by adding it slowly to a mixture of formaldehyde and weak bases like hydroxide and alkoxide. Upon slow addition of the aldehyde, the base deprotonates the α carbon of the aldehyde to form the corresponding enolate. The enolate subsequently attacks the formaldehyde to form a single crossed product. Figure 1 depicts the aforementioned reaction.
