Horizontal
If the sound of a bell ringing at 80 dB SPL (i.e., the test tone) is judged to be as loud as a 1000-Hz tone at 60 dB SPL (i.e., the reference tone), then the loudness level of the bell in Phon is:
60
The perceived loudness of a sound is dependent on its frequency.
True
What is the term for the amount by which one stimulus must be different from another for a person to notice the two stimulus are different.
Just noticeable difference
