Stetho
S1 < S2/Normal
Heart Sounds-1
Normal heart sounds at the base (aortic and pulmonary valve site) are S1 < S2 . S2 generated when the aortic and pulmonary valves close almost simultaneously.

Stetho
S1 > S2/Normal
Heart Sounds-2
Normal heart sounds Apex (mitral valve area) heart sounds are S1>S2, and S1 is generated when the mitral and tricuspid valves close almost simultaneously.

Stetho
Tracheal sounds
Lung sounds-1
Tracheal breath sounds are broad frequencies heard over the trachea, sometimes as high as 1000 Hz. The duration of inspiratory (Insp) vs expiratory (Exp) phase is 1：1, although Exp phase might be longer than that of Insp. The frequency ranges distributed between200 Hz to 2000 Hz.

Stetho
Bronchial sounds
Lung sounds-2
Sounds heard around the carina at the level of Lewis angle with intermediate frequency. The frequency of bronchial sounds is lower than tracheal sounds, while, higher than in vesicular sounds. Inhalation：Expiratory time is considered as 1： 2, but in some cases 1： 1. Although bronchovesicular sounds are noted at peripheral lung fields (Insp vs Exp time is 1：1), which can hardly discriminate from bronchial sounds, thereby not discussed here.

Stetho
Vesicular sounds
Lung sounds-3
Recognized in the whole lung fields, and the ratio of inspiratory： expiratory time is 2：1 to 3：1. Audible like a breeze, low pitched sound only on inspiration and usually cannot recognize on expiration. A forced inspiration (Inhale vigorously) can make the alveolar breath sound more louder.

Stetho
Gulu sounds
Bowel sounds-1
Peristaltic sounds propagate throughout the abdomen, so 1 ~ 2 auscultation positions are sufficient / Normal: At least 5 times per minute, Decreased: 1 ~ 2 times per minute (Constipation, peritonitis, paralytic ileus, decreased bowel movement due to surgery), Loss: No crackles for 5 minutes (Functional ileus and peritonitis), High: Always heard (Infectious enteritis, diarrhea, intestinal obstruction).

The cardiology patient simulator "K" was developed in 1993. In 1997, its educational effectiveness of this study was reported in CARDIOLOGY. Even today, most of the university medical schools and medical colleges in Japan as well as many foreign countries have been using this simulator for their educational activities.
The advancement in diagnostic instruments using high technology has been remarkable in the last few decades. However, there is a tendency for many clinicians to become too dependent on these highly sophisticated instruments and to forget the importance of bedside clinical skills.
I believe that we have an excellent inborn sensor to recognize "organ language" and are able to detect minor changes of physical findings, such as heart sounds or murmurs of heart diseases.
The Kikuzo speaker is used as an exciting teaching tool, whenever and wherever the self-learning of auscultation is needed. Please start with normal heart sounds and advance to each case at your own pace. So, you will be able to recognize various abnormal sounds and murmurs. The "Kikuzo" will be a great auscultation aide for you.

Physicians can use the stethoscope whenever they want, which is an indispensable tool for discovering the etiologies and/or patients’ disease status even after the timing of modern technologies were applied.
Furthermore, auscultation itself can give preferable emotional effects with the confidence for patients.
Physicians should image the lung sounds for individual respiratory diseases just before performing auscultation.
Learning of auscultation skills for discriminating respiratory diseases needs consideration for specific lung sounds in accordance with the anatomic location.
In this regard, the “kikuzo and its website” will provide an important and useful lung sounds for physicians, which can clearly and reproducibly learn the representative and/or essential lung sounds in general practice.

I remember 35 years ago when I first realized, “I have finally grasped the art of auscultation!” As a new intern I was assigned to the cardiology ward where one of my tasks was to listen to the chest sounds of a patient with five different cardiac conditions: mitral valve stenosis, mitral valve regurgitation, aortic valve stenosis, aortic valve regurgitation, and tricuspid valve regurgitation. But all I heard was a whirring sound and had no idea what it was. From that day on, every morning when I went to the ward, I spent dozens of minutes auscultating her chest. One day, about 10 days later, I suddenly heard several distinct sounds. I was able to differentiate the sound of mitral stenosis from that of aortic regurgitation. Auscultation is not something that can be understood by attempting it once. Listening carefully over and over again is what turns a noise into meaningful sounds. It is said that auscultation is not done with the ears, but between the ears. I encourage everyone to train what lies between the ears by listening carefully again and again.
