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.
A foramen is an opening in a vertebra through which the nerve roots leave the spine. Each vertebra has two foramina, one on either side. From the foramina, the nerve fibers travel to all regions of the body.With foraminal narrowing, this opening becomes partially blocked, causing a painful compression of the nerves.oraminal narrowing can be a very painful condition and should be diagnosed as early as possible. MRI, CT, and X-ray equipment can all help your doctor to make a firm diagnosis. Often pain medications and physical therapy are not enough to combat the symptoms of foraminal narrowing.
