Lung diseases should be taken care of seriously without ignoring them. We can’t be sure what kind of disease we have developed until we visit a doctor.
Sometimes we might find symptoms and sounds from the lung area. Then it could be a sound of rales or the other problem which is called crackle. Finding it at the right time will help us to avoid future complications.
Rales vs Crackles
The difference between Rales and Crackles is that Rales is a type of crackle, and sometimes people will call it crackle as well. But crackle is a sound that will come from the lungs, and it can become worse if we fail to take proper care of ourselves. Rales sound will be either continuous or discontinuous. But crackles are discontinuous.

Rales are a problem that is caused in the lung area due to the passage of airflow in the small airways. This kind of problem will cause some sounds, and you can feel that as well.
Sometimes the sound might be very huge, and, in some cases, it will be very small. No matter whatever the sound is, we should consult a doctor immediately without making any further delay.
Crackles are a lung disease that could become worse if we fail to take proper care of them. Only proper medication, treatment, and rules will help us to avoid the complications that will happen after a long time.
This kind of sound can be heard well only with the help of a stethoscope. Even if you hear it without a stethoscope, then it is time you should visit a doctor without making delays.
Comparison Table
| Parameters of Comparison | Rales | Crackles |
|---|---|---|
| Affected area | Lungs | Lungs |
| Sound | Can be heard | Can be heard with the help of a stethoscope |
| Discontinuous | It will change | Yes |
| Treatment | Yes | Yes |
| Heard When | When we inhale the air | When we exhale the air |
What are Rales?
Rales are a sound that is formed in the human lungs. This kind of sound will happen when the lungs get shaken or something happens. Even this type of sound will be heard when we breathe in and out.
This can be dry or moist as well. Our lungs used to contain a small airway. In this airway, the sounds will travel. When we hear the sound, it will be like a small crack.
The sound might sometimes be very large. The sound can sometimes be very fast, and we have to make sure that the sound is affecting us or not.
If it often occurs, then it would be better if we visit a doctor without ignoring it. Only doctors know the treatment, and they will help us in avoiding it. Any kind of problems in the lungs should be taken care of very seriously.
Because lungs are the part of the body that helps us in breathing. If we avoid the problems in the lung area, then it will affect our breathing. If our breathing gets affected, then other complications will arise.
So, the sooner we consult a doctor, we can get some good relief out of that problem. This kind of rales is caused by some of the openings that occur in the small airways and also at the alveoli.
What are Crackles?
Crackles are sounds that are caused in the lung area. This kind of sound can be observed only with the help of a stethoscope. But if we hear any sound while breathing, then it is called a different type of crackle, and that is called Pulmonary crackle.
They can together cause other health-related conditions as well if we fail to take care of our lungs or if we avoid the problem and ignore it.
Having a crackle-related disease itself is a huge burden for us, and some other diseases will be more burdens for us. Sometimes this kind of crackle-related disease will cause pneumonia, and in other cases, it will lead to heart failure as well.
No matter what kind of lung disease we have, it will create a huge impact on our human body and will lead to several other complications as well.
The sound of the crackle will be like a rattling one, or in some cases, it will be very discontinuous. It will be like if we drop some water in hot oil, it will create a crack-like sound. The same will happen in the crackle of our lungs.
There are some types of crackles, and the most severe one among them is the bibasilar crackle. If we find it earlier and take care proper care and treatment, then we can avoid the long-term complications.
Main Differences Between Rales and Crackles
- The sound of rales can be heard when we inhale the air. On the other hand, the sound of crackles can be heard when we exhale the air.
- Rales can be heard normally without any instruments, but it is not the case all the time. But crackles can be heard with the help of a stethoscope.
- The sound of rales will be very much high, and the tone of the sound will be high-pitched. On the other hand, the sound of the crackles will be somewhat lower and mild.
- Rales is a type of crackle, and it is not further divided into categories. On the other hand, crackles are alveolar rales, and it is divided into fine and coarse.
- The rales are caused by the small airways, and they could sometimes be discontinuous. But the sound of the crackles is discontinuous.
