Objectives

Labeled pictures with explanations on how the devices operateConclusionReferencesObjectives Learn hearing and sight limitations

Learn how to overcome limitations of our sight and hearing by using or wearing technology devices

Learn the common technology devices that make our live easier

Three examples of hearing devicesHEARING DEVICESFUNCTIONSStethoscopeHearing aids

Loudspeaker

ConclusionsWith science research, human has found ways to explore beyond our general hearing frequency limitation (12Hz to 20KHz) with the Stethoscope, hearing loss due to aging with the Hearing Aid or damping of sound level over distance with the loudspeakers.

Apart from sound, human has also found innovative ways to overcome direct line of sight limitation with simple innovation such as Periscope to Binoculars to overcome distance or complex elements such as virus discovered in medical equipments.

As a whole, science has created great impact to human lives and technology advancement.ReferencesTho Lai Hoong, Hasnah binti Abu Samah, 2003. Science Form2 Volume 1. Sasbadi Sdn. Bhd.
