Hearing Aids these days have grown from seldom used components to the oft favoured variety. They have generally been shunned by the larger crowd due to their obtrusive nature and tacky appearance, but not now. This difference in public perception and new found acceptance stems mainly from their increasing efficiency, reducing size and less obtrusive nature. These days, there are two types of hearing aids available for the general public: analogue hearing aids and digital hearing aids. These two types vary in the way in which they function though the base cause remains the same, that is, amplifying the sound for the listener to perceive and hear.

Digital hearing aids have been around for a long time now; their rise can be traced back to the early 1980s. Originally obtrusive, large and unattractive, their acceptance grew with the rise of the digital age which resulted in a direct cut down in their overall size. Digital hearing aids are rightfully considered to be far superior to their analogue counterparts and this claim can be proved true due to a variety of aspects. Digital hearing aids make the hearing process more efficient by making the voice more audible by negating the surrounding noise to a large extent. The microphone receives the signals and converts them in to digital data in the form of bits. These bits are manipulated by the miniature computer present inside the hearing aid system, which makes sure that the sounds are processed accurately. Digital hearing aids are also more user friendly than the analogue types in the regard that they filter out the background noise efficiently, making it easier for the deaf to actually listen to conversations in crowded and noisy places.

Digital hearing aids also provide better quality output than their analogue counterparts. This further adds weight to their ensuing prevalence over analogue hearing aids, not to mention the fact that they are programmable and can be varied to suit the requirements from person to person. They should be programmed and set up by a person who is skilled in the specific field for them to work wonders, so making sure your audiologist is well qualified is a start. The primary hearing test is generally used to confirm the frequencies and sounds that the specific patient can’t decipher or make out. The bands of sound that the patient is hard of hearing are amplified using the audiologist’s computer and the sound recognition is perfected over long hours of testing. Hence these digital hearing aids provide better efficiency, they are lighter and portable and hence, more preferred than their counterparts.

The countries receiving radiant energy through out the year, make use of Solar Heating to cook food. The Solar Cooker functions using the Black Body Effect, i.e., a Black Body absorbs 98% of the energy incident on it.

These cookers are painted black on the outside and inside. The food to be cooked is placed in metal boxes painted black on the outside but polished and clean on the inside. The food is put in these, and then placed inside the cooker. The cooker has a glass lid  – to create the greenhouse effect inside the cooker – the closing lid of the cooker is the outer most and fitted with a mirror which is fixed at an angle, facing the sun to direct the solar heating into the cooker.

The Solar Heating or the solar lighting, cooks the vegetables and lentils slowly over the day and are ready to eat by late afternoon.
