The technique is called percussion.
Density can be used to determine the mass and the volume of a given solid.
The definition of density is mass divided by volume.
divide mass and volume(:
To determine the substance given the mass, you would need to compare the mass to the known density of various substances. By dividing the mass by the volume (which can be calculated from the dimensions of the object), you can determine the density of the substance. Then, you can compare this density to known values to identify the substance.
To find the density of marbles, you would measure the mass of a certain number of marbles using a balance scale, then calculate the volume by either measuring the dimensions and using a formula for the shape of the marbles or by displacement method with water. Finally, divide the mass by the volume to determine the density of the marbles.
Tapping the chest to determine density is known as percussion. During this diagnostic procedure, a healthcare provider will tap on different areas of the chest to listen to the sound produced. Dull sounds may indicate denser tissue or fluid accumulation in the lungs or chest cavity, while hollow sounds may indicate normal air-filled lungs.

The mass divided my the volume determine the density of an object
Your primary care doctor can set it up for you to have a low dose x-ray which will help determine your bone mineral density. A radiologist will perform the procedure and relay the results to your doctor.
Density can be used to determine the mass and the volume of a given solid.
To determine the relative density of a substance, you can divide the density of the substance by the density of water. The relative density is also known as specific gravity and helps compare the density of a substance to that of water.
The formula for density is an object's mass, divided by its volume. If you have both those quantities, you can determine the object's density.
You multiply the density by the volume.
Mass = Density Volume
The two factors that determine a material's density (such as that of wood) are its mass and volume.
The density of the mineral compared to the density of water will determine if it floats or sinks. If the mineral has a lower density than water, it will float; if it has a higher density, it will sink.
Density in general is found by Mass divided by the volume
