Hearing01:31

Hearing

52.5K
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.

Larynx01:21

Larynx

1.7K
The human larynx, often referred to as the voice box, is an intricate organ located in the neck. It serves as a pathway for air to enter the lungs during respiration and is an essential component of voice production.
Anatomy of the Larynx
The larynx consists of various components, including cartilage, muscles, and vocal cords. Its structure includes three large unpaired cartilages—the thyroid, cricoid, and epiglottis—and three smaller paired cartilages—the arytenoids,...

Effects of feedback01:24

Effects of feedback

608
Feedback in control systems plays a critical role in shaping various operational parameters, extending beyond simple error reduction to influence stability, bandwidth, gain, impedance, and sensitivity. Understanding these effects requires examining a basic feedback system characterized by defined input, output, error, and feedback signals.
Feedback significantly modifies the gain of a control system. The gain of a system without feedback is altered by a factor of one plus GH, where G represents...

Auditory Perception01:17

Auditory Perception

384
The auditory system is essential for sound perception, utilizing various critical structures. When sound waves enter the outer ear, they travel through the ear canal and cause the eardrum to vibrate. These vibrations are then transmitted to the middle ear, where three tiny bones – the malleus, incus, and stapes – amplify the sound. This amplification is crucial, as it ensures that the sound vibrations are strong enough to be conveyed to the inner ear. These vibrations then reach the...

Sound Intensity00:58

Sound Intensity

4.1K
The loudness of a sound source is related to how energetically the source is vibrating, consequently making the molecules of the propagation medium vibrate. To measure the loudness of a source, the physical quantity of interest is the intensity. This is defined as the energy emitted per unit of time per unit of area perpendicular to the sound wave's propagation direction. Since the total energy is greater if the source vibrates for a longer duration and over a larger area, dividing the...

Sound Intensity Level00:53

Sound Intensity Level

4.2K
Humans perceive sound by hearing. The human ear helps sound waves reach the brain, which then interprets the waves and creates the perception of hearing. The loudness of the environment in which a person is located determines whether they can distinguish between different sound sources.
The human ear can perceive an extensive range of sound intensity, necessitating the use of the logarithmic scale to define a physical quantity—the intensity level. It is a ratio of two intensities and...

Summary

The Australasian College for Emergency Medicine (ACEM) supports an Aboriginal Voice to Parliament. However, the proposal lacks detail, and ACEM

Area of Science:

  • Public Health
  • Indigenous Health
  • Health Policy

Background:

  • The Australasian College for Emergency Medicine (ACEM) has endorsed the Aboriginal Voice to Parliament proposal.
  • This endorsement aims to improve health outcomes for Aboriginal and Torres Strait Islander people and ensure culturally safe emergency department (ED) care.
  • The Voice proposal has become a politically contentious issue with limited operational details available.

Purpose of the Study:

  • To critically evaluate the ACEM's endorsement of the Aboriginal Voice to Parliament.
  • To assess the factual basis and speculative claims within the ACEM's statement.
  • To examine whether ACEM's engagement in political matters aligns with its core mission.

Main Methods:

  • Critical analysis of the ACEM's public statements and the Aboriginal Voice proposal.

  • Review of existing evidence regarding the potential impact of such a Voice on Indigenous health outcomes.
  • Assessment of ACEM's organizational remit and strategic priorities.

    • Main Results:

    • The ACEM's claims regarding the Voice appear speculative, lacking concrete evidence of intended outcomes.
    • There is insufficient detail on the proposed Voice's operational mechanisms and effectiveness.
    • ACEM's involvement in this political debate may detract from its primary objectives.

    Conclusions:

    • The ACEM's endorsement is based on speculative claims rather than established facts.
    • ACEM may be exceeding its mandate by taking a stance on a complex political issue.
    • Focusing on political advocacy risks diverting resources and attention from ACEM's core mission of improving emergency care and health equity.
