Responsibility/Biomimicry
SiM is a product that will allow music to be controlled and monitored by the individual. It is their responsibility to turn down their music when they know it is too loud. The product will show when the music is too loud or if they have listened to music too long. This will advise the person to turn it down and rest their ears, allowing the hair cells to have a break and not overwork themselves to generate sound. This is a completely unique and new product because the music that is actually being played will be measured and the product is attached to the music source. Some of the main components in the product are also energy efficient. This product relates to biomimicry because it is converting unit of energies or a type of energy transformation. This occurs in everyday life, for example in the transcription/translation process in DNA to proteins. This occurs when an organism eats a type of food. For example, when a herbivore digests plants, those plants turn into a form of energy for them. The hair cells inside the ear convert mechanical energy into electrical energy. A solar cell converts light into electrical energy. All these processes use energy transformation. Now the product will not actually convert the energy itself, however it will convert the units.
Ammeter
Ammeters (also known as amp meters) measure a wire’s magnetic field, thus determining how much current is flowing through the wire. The current, amount of electrical charge passing through a circuit in a specific amount of time, is measured in amperes.
Clamp-On Ammeters
Traditional ammeters tap directly into the wire, which can actually give a false reading as the ammeter’s resistance (in ohms) changes the device’s resistance, and thus the current.
Clamp on meters, however, do not break into the wire. They measure the magnetic field of the wire, and do not add any resistance to the circuit, making it a very accurate way of measuring amps.

SiM's Ammeter
SiM uses a digital current transformer clamp-on ammeter. You can see why we just went with SiM. Anyway, the ammeter has a set of jaws that are made with a ferrous carbon metal – like ferrite. Around these jaws is a metal coil with a current running through it. When the current flows through the wire, it produces a magnetic field. When the magnetic field hits the jaws, it breaks the ammeter’s magnetic field. When the ammeter’s field breaks, magnetic signals are sent through the coils, which become electrical signals – a current equal to that of the wire being measured. As the current passes through the wires and transistors, it comes to a reading point before it enters the calculating circuit. In the calculating circuit is where the current is changed into data for the display screen, with the help of a transducer. In SiM, however, there is one more step before the data is displayed.
Microprocessor Chip
This main component will calculate or analyze the amount of electrical energy (amperes) to the sound unit (decibels). The information will be directed through a control unit. This control unit will take the already added information from the main memory and will decode it into commands. Then it will send off the commands to the arithmetic logic unit (ALU). This unit is a digital circuit that can perform various integer operations. The unit will execute these commands and then store back into main memory.
This equation will be entered into the microprocessor chip to convert from amperes to decibels.
(A)= amperes, dbA= decibels in reference to amperes (20) = standard reference level log= logarithm
Equation: A to dBA dBA= 20log(A)

Simple microprocessor
The microprocessor is used for moving data from one place to another and making a new set of instructions and then carrying them out. The simplest microprocessor contains an address bus, data bus, RD, WR, clock line, and reset line. The address bus sends an address to memory. The data bus can send or receive data from memory. An RD(read) and WR(write) are lines that tell the memory where to send or get the addressed location. The clock line is a timer or clock sequence for the processor. The reset line can restart execution. The registers A, B, and C are just latches as is the address latch. Latches are just multiple inputs that can reset or set outputs of information. The program latch can increment more than one and can reset at zero. The ALU unit performs mathematical information. The test register is a latch that can compare two values. The six boxes are known as tri-state buffers. These buffers allow multiple outputs to connect to a wire. It can also easily disconnect its output. The information decoder and information register decodes and holds the information.
Liquid Crystal Display(LCD) Screen
This display uses light properties coming from liquid crystals. These display screens can emit words and numbers. This product is used on computers, television monitors, calculators, watches, alarm clocks, and portable electronic devices such as the iPhone. LCD's are energy efficient because of its low power consumption. It is also very light. The screen uses two sheets of polarizing material containing a liquid crystal solution between the two. An electric current passes through the liquid which causes the crystals to form or align together so that light cannot pass through. The crystals act as a shutter and opens or closes, allowing the pixels of light to be passed or blocked. The crystals are colorized and the image becomes visible. This specific LCD screen will show the average intensity of the decibels and the duration of the music. Not only will it show the time and intensity, but it will also be programmed to show if the time and intensity is in the danger zone for risk of NIHL. A thin-film transistor or active- matrix displays will be used for its sharp image quality. In these color displays, each pixel contains a transistor. This allows the electric current radiating to be switched on and off at a faster rate, making the display brighter and imaging smoother. This way, any number of colors can be visible to the eye.
LCD
There is a mirror in the back which allows it to be reflective. Then there is a piece of glass with a polarizing film on the bottom. After that, there is a common electrode plane made of indium-oxide on the top. Next, there is a liquid crystal substance and after that, there is another electrode. Finally there is a polarizing film along with a glass filter at a right angle to the first polarizing film. When there is no electrical current, the light will simply bounce back from the mirror. But if there is an electrical current, the liquid crystals from the common-plane electrode and the rectangle-shaped electrode untwist and block the light passing through it, This happens due to the angles not matching up, creating a dark portion in the display area.
