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. 

    racial conflict and discrimination has existed ever since man learned to kill with rocks and bones. these conflicts arose from disputes between territory, power, wealth, religion, or simple difference. some of the most infamous racial disputes include slavery, the holocaust, and the civil rights movement.

    these listed disputes often resulted in casualties from all sides. riots, wars, imprisonment, and lynching are all commonly associated with racial conflict on severe levels.

      however, racism is an improving issue in recent decades. people are being more accepting and welcoming of diverse populations. though, the world isn't perfect and it will take much more time, if ever, until the world is rid of racism.
