Jamal was having his hearing tested,and a number of the tones that were presented were so faint he was not able to detect them.What can you say about the faint sounds

A)  They are below Jamal's absolute threshold for sound. 
B)  They cannot create a just noticeable difference. 
C)  They cause weak action potentials. 
D)  They fall below Jamal's adaptation level for sound.

Absolute Threshold

The minimum intensity of stimulation required to produce a sensory experience or for a stimulus to be detected 50% of the time.

Just Noticeable Difference

The minimum amount by which stimulus intensity must be changed in order to produce a noticeable variation in sensory experience.

Action Potentials

Quick electrical impulses that travel down the axon of a neuron, triggering the release of neurotransmitters at synapses.
