Pavlov's dogs are the most well-known examples of associative learning. Whenever Pavlov fed the dogs, he would ring a bell, so eventually when the bell rang the dogs expected food.
Here is how you use dispersed in a sentence, "The groups of lions were dispersed by the game rangers." This means to scatter or spread out.
We refer to a conditioning stimulus and conditioned response. The conditioning stimulus is feedback that creates, enhances or intensifies a reaction, which is the conditioned response. In a famous series of experiments by Dr. Ivan Pavlov in the late 19th Century, dogs drooled when he gave them food and rang a bell rung at the same time. After awhile the dogs drooled at just the sound of the bell. The sound of the bell was the conditioning stimulus, and the physiological reaction of salivation in the dogs was the conditioned response.
For frequency ranges, we can hear from 20 Hz to 20000 Hz (20 kHz). This is due to a limit on the length of our cochlear basalar membrane. If it were longer, we may be able to hear a greater range. For loudness, using a standard pressure level (SPL) absolute value system, we can hear at soft as 20 dB SPL (just audible whisper) to about 120-140 dB SPL (which will begin to cause hearing loss and irreversible damage).

"I rang the doorbell" is correct. "Rung" is the past participle of "ring," not the past tense form used in this context.
"You rang the doorbell" is an indepent clause, because it can exist on its own. So is "but no one answered," because it is using a coordinating conjunction, which acts as a independent marker for an independent sentence. See https://owl.english.purdue.edu/owl/resource/598/01/.
The independent clause is 'When the doorbell rang.' It is an adverbial clause, modifying the verb 'was sleeping'.
Had is a past tense, which means it happened before (eg Sally had rung the doorbell) rang counts as a present tense (eg Sally rang the doorbell) The appropriate word for "had" would be "had rung" which is past tense.
