Burow's solution is an aqueous solution of aluminium triacetate.It is available in the U.S. as an over-the-counter drug for topical administration, with brand names including Domeboro (Moberg Pharma), Domeboro Otic (ear drops), Star-Otic, and Borofair. [1]
In electronics, an immittance Smith chart can be created by overlaying both the impedance and admittance grids, which is useful for cascading series-connected with parallel-connected electric circuits. This allows for the visualization of changes in impedance or admittance in the system caused by components of either the series or parallel circuit.
[4] [5] The impedance matching is done through via lever ratios and the ratio of areas of the tympanic membrane and the footplate of the stapes, creating a transformer-like mechanism. [4] Furthermore, the ossicles are arranged in such a manner as to resonate at 700–800 Hz while at the same time protecting the inner ear from excessive energy. [5]
To deliver maximum power to the load, the impedance of the driver should be the complex conjugate of the impedance of the load. In the case of a purely resistive load, the resistance of the driver should be equal to the resistance of the load to achieve maximum output power. This is referred to as impedance matching. Intermodulation distortion ...
The purpose of the middle ear ossicles is to overcome the impedance mismatch between air waves and cochlear waves, by providing impedance matching. Also located in the middle ear are the stapedius muscle and tensor tympani muscle, which protect the hearing mechanism through a stiffening reflex. The stapes transmits sound waves to the inner ear ...
The middle ear matches mechanical impedance, like a lever. Ordinarily, when sound waves in air strike liquid, most of the energy is reflected off the surface of the liquid. The middle ear allows the impedance matching of sound traveling in air to acoustic waves traveling in a system of fluids and membranes in the inner ear. This system should ...
