Audiometry - Lab Report Example The conduction testing of the air presents stimuli to both ears but independently using some special earphones. The stimuli is reduced while going from the test ear to the cochlea of the others ear. This is energy loss is known as the interaural attenuation which ranges between 45 – 80 dB. However, stimulation occurs to the cochlea in both ears. As a result, cross hearing is a situation to consider more in the conduction of bone than in the conduction of air (Yoon et.al 469). The mastoid process of the proper ear is used to transmit pure tones by placing vibrator bone over it. The results of the experiment may be determined by the placement of the vibrator as well as the pressure. Technical factors and distortion may cause may limit the output of the audiometer to about 80 dB. The non-test ear should always be eliminated from the procedure whenever the cross hearing is suspected. In order to remove the non-test ear from the procedure in case of any suspected cross hearing, is to mask by delivering noise to the non-test ear (Yoon et.al 469). The loudness of the masking procedure should be able to prevent the tone reaching the non-test ear and stimulating it. This experiment aims at determining the threshold hearing over a variation of frequencies. The experiment may test the bone conduction also known as the vibrator as well as the air conduction or the loudspeaker. But the audiometer can only test the air conduction also known as the loudspeaker. The procedure of performing the experiment was the same for two different partners. The first thing was to check and confirm that the connection of the audiometer and the headphones was not loose. The experiment was conducted in a silent laboratory. My partner put on the headphones while I adjusted the volume of the audiometer over the required frequencies. The hearing threshold was determined for every frequency. The button was used to

Using social media in business opportunity and risk (Facebook) Personal Statement

Using social media in business opportunity and risk (Facebook) - Personal Statement Example Forums for interactions that the media, such as Facebook, offer allow organizations to understand their customers need and to tailor their products for meeting these needs. It also helps in identification of markets that aid sales and market control. Availability of a pool of customers or potential customers, cost efficiency and cost effectiveness are some of the opportunities that Facebook offer to corporate organizations. Cost effectiveness of Facebook, for instance, while it ensures effective access to target audience, in strategies such as marketing and customer relationship management, facilitate the profit motive. Facebook also allows a business an opportunity to collaborate with other businesses for common interests and this is possible through interactions in professional groups (Belleghem 191). Reliance on social media such as Facebook however reduces interactions with customers for in-depth communications and this may be a barrier to understanding and meeting customers’ needs. There is also risk of insecurity over data because of sharing of information on Facebook. In addition, technicalities with the media, such as when it shut down, may impose temporary limits to information access (Payne & Frow 388; Belleghem
