Finally, they were distributed to Conan, Fujiwara and Reiko Akito, three wired headphones and three answer books, while the connections of the three wired headphones have been connected in advance to the multi-head interface of a music broadcaster next to them.

"Get ready to start," sat casually next to the broadcasting machine. Gregory looked at the three of them and signaled that they were ready, and pressed the play button to start the test audio. "go!"

[First question, you will hear multiple pure rhythm sounds with 440Hz as the reference. The tone may be normal pitch, or slightly higher or slightly lower than normal pitch. Please record the differences between all pitches you hear and the standard tone. Please note that some pronunciations may be special or composed of multiple tones.]

"Special tone?" Conan held the pen and tapped the answer book nervously with the tip of the pen. "What's the special method?"

At this moment, the first note rang - this was a slightly higher than the standard mi.

【Mi+】——Conan

【E3+】——Fujihara

At the same time, Qiu Ting Lianzi also calmly wrote down her listening results in her notebook.

【411】

The pronunciation is the meaning of the number written by Aki Ting Reiko - if C3 is used as the reference, then the pitch frequency Hertz number of C4 (treble do) is exactly twice that of C3. If C3 is used as the reference point, C4 is 1,200 points higher than C3. And Aki Ting Reiko means that this sound is 411 points higher than C3, and the pitch frequency is 2 (411/1200) times the power of C3, which is about one quarter of Mi.

The next question immediately made Fujiwara, the only one among the three without absolute sound, show a shocked expression. Then he looked at Gregory in confusion, then looked at Reiko Aki Ting, who was smiling and Conan, who wrote an answer with a somewhat uncertain expression after thinking for a while.

【Absolute sound...is it a monster?】

The reason why Fujiwara raised such confusion was that a crisp clapping sound came from the headphones. Yes, the test required them to hear the pitch of the clapping sound.

For ordinary people, such a sound cannot be associated with something like pitch at all, but for the owner of absolute sound sense, the two will never be at all.

The next note has returned to the normal piano note. Although Fujiwara was a little disappointed in the previous question, he was still ready to identify the note in the fullest state, but he found that the note was a bit strange: Compared with the normal note, it seems a bit... strange?

Where did this feeling come from? Fujiwara frowned and chewed the tone carefully. But he also knew that he had to make a decision as soon as possible, betting that his anxiety was just an illusion or something was true.

He finally chose to think that this sound is indeed a bit strange, and the strange reason is that after careful savoring, this sound is lower than the standard sound.

【B4-】——Fujihara

[1086]——Riko Aki Ting's answer had been written before him. Obviously, she had indeed received much better training than Fujiwara in this regard, and also had much better talent, so she was still at ease. While Fujiwara was still hesitating whether there was really a gap in this, Reiko Aki Ting had to be much more certain: B4, that is, the si's pronunciation score was 1088, and although this sound was not much worse, it was indeed lower than the standard si.

But when I wrote this, even Riko Qiu Ting was a little confused - although this sound is indeed lower than the standard sound, this headphone is an electronic product after all. If these sound differences come from the failure of machine conduction, then this experiment will be meaningless.

And the next sound - to be precise, the following group of sounds made Aki Ting Renzi feel a little funny.

That was the alarm sound from NHK TV station. When Emperor Showa passed away, he used to... No, this seemed to be longer than the music of Emperor's death, and it seemed to have been processed with a change of tone, which is different from the string of sounds in Aki Ting's mind. But... it's still not difficult, right?

(This is the change of the tone of the alarm when Japan issued a declaration of war)

Thinking of this, Reiko Aki Ting wrote down all the answers casually, but found that although Fujiwara's reaction was quick, Conan seemed to be completely stumped by the question, and he didn't write anything, and his face was completely confused.

Is this question... difficult? Not difficult!

Fujiwara, who was beside him, soon realized Conan's predicament, and Gregory seemed to have expected this incident.

After that, there were two more chord tests, a set of extremely short and complex piano chords and a burst tone chord of the electric guitar that lasted relatively long. After these two chords, the first part of the test question ended. Then the sound of the symphony sounded, and Gregory also handed three scores to the three. "Look, it's the thing on it, and carefully see if there are any notes that were played wrong."

Brahms's first symphony in C minor may be a little confused by those who are not familiar with the music, but all three of them know that this is a track with a total length of more than 45 minutes.

It seems to be a pretty boring and protracted war.

...

After 55 minutes.

"So, what's the use of letting us listen to those songs just now?" After finishing the set of questions that were similar to those of the first symphony, Conan looked at them and clapped, congratulating Gregory who had completed the test, and said speechlessly. "It's obvious that there is no problem anywhere, but we're wasting so much time."

"Yes, isn't it a bit too tormenting," Fujiwara also showed a pretty tired look. "Is it really a serious test, not a torture for us?"

"Well, of course this is a test," Gregory glanced at Riko Qiu Ting, who had a mysterious smile beside him. "Well... let's compare the answer. Considering Miss Riko's skills, it's okay to let her answer be the standard answer."

Low normal sound - clapping - slightly lower normal sound - declaration of war alarm - piano chords - electronic music chords

Among these six test questions, although half of Fujiwara and Conan can achieve the same direction as Reiko Aki Ting's answer (which is completely incomparable in accuracy), they each have two questions and three questions different from Reiko Aki Ting's answer.

Fujiwara could not hear clapping and piano chords that were difficult to identify because of too many stacking of notes. This was within the range that everyone could expect. After all, the former does require absolute sound, while the latter is too complicated.

But as a person with absolute sound, Conan made more mistakes.

He could not hear the second normal voice slightly lower than normal si, but directly filled in the normal si. In the two questions of declaration of war alarm and electronic music chords, he simply handed in the blank paper.

And even more amazing things are still to come.
