To get power in our houses and businesses, there are several processes that the power goes though to get generated and carried across miles of power lines. Electricity is generated in a thermal power plant, hydroelectric power plant, and nuclear power plant, etc. This electricity is then supplied to a transmission substation near the generating plant. In the transmission substation the voltage is increased substantially using step up transformers. The voltage is increased to reduce the transmission

Hearing loss and Decibels To understand decibels and hearing loss we first need to understand what and how decibels are and measured. The decibel (dB) is used to measure sound level. It is the logarithmic way of describing a ratio. This ratio can be power, sound pressure, voltage or intensity or several other things. For the case of hearing loss we will use decibels to determine the sound pressure. Sound pressure is the force of sound on a surface area perpendicular to the direction of the sound
