A sound that is 10*10*10*10 or 10000 times more intense (1*10-8 W/m2) is assigned a sound level of 40 db. Observe that this scale is based on powers of 10. If one sound is 10x times more intense than another sound, then it has a sound level that is 10*x more decibels than the less intense sound.
What is the difference between foraminal stenosis and spinal stenosis? Foraminal stenosis is a narrowing of the opening in the sides of the vertebrae where the individual spinal nerves exit the spinal canal and go out into the arms and legs. Spinal stenosis refers to narrowing of the central spinal canal where all the nerves and spinal cord run through.
In most cases of foraminal spinal stenosis, the foramen on one side of the vertebra is affected, so the symptoms are felt on one side of the body. However, bilateral foraminal stenosis means that both sides of the body are affected because both the left and right-branching foramina have narrowed.oraminal stenosis symptoms include pain in the affected region of the spine as well as pain, tingling, weakness, and numbness in other parts of the body.
