Often occur in pairs with low pass filter, no matter any, be provided to certain sound frequency to deliver to the unit that go.Low
Bandpass filter is to allow to pass through less than the signal of cut-off frequency, but higher than the signal intransitable electronic filtering dress of cut-off frequency
Put.For different wave filter, the signal of each frequency to weaken degree different.When using in voice applications, it is sometimes
It is referred to as highdensity plywood wave filter, or high pitch eliminates wave filter.
And high pass filter is a system making altofrequency be easier by and to stop low frequency to be passed through.It eliminates
Low-frequency component unnecessary in signal eliminates low-frequency disturbance in other words.Its characteristic can be rung with impulse in time domain and frequency domain respectively
Answer and frequency response describes.
Further, heart sound refers to the sound produced during heart contraction diastole, and available ear or stethoscope are heard at thoracic wall, also
Available electron instrument record gets off.First heart sound, second heart sound can be divided into, and the most all can hear.And the 3rd
Heart sound, the most only can hear when child and adolescence, fourth heart sound is rarely heard under normal circumstances.Produce from heart
Heart sound lead pass to thoracic wall surface through the medium of tissue, wherein best with bone conduction, blood and muscle take second place, lung and fat group
Knitting worst, so listening the heart sound compared with normal recorded artificially light in emphysema and fat patient from thoracic wall, amplitude is low.Normal heart
The heart sound frequency produced in easypro contracting activity is 1～800Hz.People's audition than more sensitive be wherein 40～400Hz frequency band,
