| 1. | The absolute threshold is defined statistically, often as an average of all obtained hearing thresholds.
|
| 2. | It was at the absolute threshold of audibility, where it might have been real or imagined.
|
| 3. | The lowest equal-loudness contour represents the quietest audible tone the " absolute threshold of hearing ".
|
| 4. | Several psychophysical methods can measure absolute threshold.
|
| 5. | A universal absolute threshold is difficult to define a standard because of the variability of the measurements.
|
| 6. | The absolute threshold for touch is the minimum amount of sensation needed to elicit a response from touch receptors.
|
| 7. | A second absolute threshold for vision involves the minimum photon flux ( photons per second per unit area ).
|
| 8. | The absolute threshold for smell is the minimum amount of sensation needed to elicit a response from receptors in the nose.
|
| 9. | The absolute threshold for vision is the minimum amount of sensation needed to elicit a response from photoreceptors in the eye.
|
| 10. | The absolute threshold for taste is the minimum amount of sensation needed to elicit a response from receptors in the mouth.
