Sound Intensity Level00:53

Sound Intensity Level

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 hence a...

Sound Intensity

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 emitted...
Intensity and Pressure of Sound Waves01:05

Intensity and Pressure of Sound Waves

The intensity of sound waves can be related to displacement and pressure amplitudes by using their wave expressions and the definition of intensity. The critical step to achieve this is to write the power delivered by the particles on the wave as the product of force and velocity and simplify the force per unit area as the pressure. The velocity of the medium's particles can be derived from the displacement.
Unlike the time average of a sinusoidal term, which is zero since it is positive and...

Area of Science:

  • Audiology
  • Speech Science
  • Psychoacoustics

Background:

  • Establishing accurate reference levels for speech audiometry is crucial for reliable hearing assessments.
  • Existing reference values may not be directly applicable to all languages, necessitating language-specific research.
  • The reference sound pressure level (RSPL) defines the speech recognition threshold level (RSRTL) equivalent to 0 dB HL.

Purpose of the Study:

  • To determine the reference sound pressure level (RSPL) for Korean speech audiometry.
  • To establish the reference speech recognition threshold level (RSRTL) for Korean bisyllabic words.
  • To compare Korean RSRTL with established values for other languages.

Main Methods:

  • Twenty adults with normal hearing sensitivity participated.
  • Puretone thresholds were measured in 2 dB steps.
  • Korean bisyllabic words were used to determine speech recognition thresholds (SRTs) at 50% correct response levels.

Main Results:

  • The mean SRT for 36 Korean bisyllabic words was 23.44 dB SPL.
  • The difference between English and Korean RSRTLs was approximately 3.44 dB.
  • The newly developed Korean bisyllabic word lists were effective in establishing SRTs.

Conclusions:

  • The determined RSRTL for Korean speech audiometry is 23.44 dB SPL.
  • Further research with a larger sample size is recommended to refine the Korean RSRTL.
  • These findings contribute to more accurate speech audiometry for the Korean population.
