They don't create matter and we know this by the law of conservation of mass. Sound waves exist as variations of pressure in a medium such as air. They are created by the vibration of an object, which causes the air surrounding it to vibrate. The vibrating air then causes the human eardrum to vibrate, which the brain interprets as sound.

When the soundwaves hit the ear drum. The pressure wave is then passed to the Cochlear, which contain tiny hairs attached to nerve endings. Each hair resonates at different frequencies. The nerves send messages to the brain, which perceives the electrical signals produced as sound.
Atmospheric pressure is the surrounding pressure around us. We live in the atmosphere and treat the atmospheric pressure as the base pressure. A pressure gauge would read 0 at atmospheric pressure. When we define the pressure in scientific way of absolute pressure, we need to add up an atmospheric pressure to the measured pressure.
If you mean "guage pressure," it is the pressure of a fluid minus the atmospheric pressure.
Different stimuli trigger sensory nerves. Such stimuli may include temperature, pressure, vibration, touch, and pain. In answer to your question, nothing sends messages to your sensory nerves. What happens is that these nerves send signals to your brain which then interprets the signals as pain, pleasure, etc. as stated above, never receiving messages.
The ear is a biomechanical transducer which converts air pressure in to an electrical signal which the brain interprets as sound.
Different levels of atmospheric air pressure affect our weather every day.
Pressure is force / area. If you divide that by force, you get 1 / area. I am not aware that this is used in any meaningful way in physics.
Hearing
Your eardrums take fluctuations of the air pressure on your ears and converts them to electrical pulses, which are sent to the brain. The brain then interprets the electrical signals as different sounds.

Surface pressure is simply the air pressure at ground level, anywhere on Earth. Sea level pressure is an adjustment made so that we can compare pressure at stations of different elevations. Sea level pressure is surface pressure if it were taken at sea level. Small differences in air pressure are important in meteorology, which is why we measure pressure precisely. The problem is that pressure is a function of elevation to first order, and weather differences to second. That's why it must be adjusted to be meaningful. Otherwise we would think that Denver, CO is always under an extreme low pressure system.

You tell me The above answer is wrong its actually Somatosensory is the part of the brain that controls your sense of touch The somatosensory system consists of millions of sensory receptors, allowing touch to be experienced throughout the body. (In contrast, the other senses can only be experienced at localized sense organs.)
Electric current from the sound card is applied to an electromagnet changing magnetic field pushes a magnet back and forth,which is attached to the speaker cone.The moving speaker cone creates changes in the air pressure which your brain interprets as sound.
There might be 2 messages on this tire pressure: one is on the tire itself. The other is on the door threshhold. My car tire reads 35 psi. but the door plate reads 30. The remote tire pressure warning operates when the tire pressure is more than 30. So, my suggestion? Use the tire pressure on the threshhold. If none is available. use the tire pressure on the tire. It's usually 35 psi but check to make sure.
