All sounds for speech vibrate at different frequencies, which is how you differentiate speech sounds. vowels are relatively low in pitch, while consonants such as l, m, and n are in the middle range of pitches. many speech sounds such as s and f are high in pitch. how would speech understanding be affected by a person with moderate to severe high frequency sensorineural hearing loss?

Speech understanding would have an effect hugely particularly if the hearing loss is merely in one range. This would let the person to not pick up or hear some letters articulated and perhaps not be able to put them together. For instance, l, m, and n are central range pitches and s and f are high range pitches. 

uses : -

1.aneroid barometers primarily measure whether pressure is rising or falling.

2.aneroid barometers are often used for reading pressure in homes and recreational boats.  

3.other uses may include barographs in meteorology and altimeters in modern aircraft.  

4.this type of barometer can announce whether a high or low pressure system is coming or whether it is becoming more intense.  

5.there are different types of aneroid barometers, such as the altimeter, which measures altitude, or distance above sea level.  

6.another example is a barograph, which is a modified aneroid barometer that provides constant readings of atmospheric pressure on graph paper.  

7.when used in this capacity, the aneroid barometer can store a week's worth of data.

android diameter a device for measuring atmospheric pressure , often specially calibrated for use as an altimeter ,consisting of a box or chamber partially exhaused of air, having an elastic top and a pointer to indicate the degree of compression of the top caused by the external air
