Vents can be added to these devices to reduce their contribution to the occlusion effect. Examples of these devices abbreviated CROS and BiCROS help alleviate adverse (-5[1])effects caused by a “single-sided” form of one condition. These devices, which have an open-fit type, are prescribed in the most common treatment used to slow the progression of presbycusis. (-5[1])“Anchored” (15[1])kinds (15[1])of these devices (-5[1])are typically (15[1]-5[1])surgically inserted (-5[1])into the (15[1])(*) mastoid (10[1]-5[2])and collect (-5[1])vibrations induced by bone conduction. (10[9]-5[1])The receivers (10[2])of BTE (10[2])kinds (10[2])of these devices (10[3])are designed (-5[1])to (-5[1])“hook” (10[1])the top of the auricle (-5[1])of their users. (10[3])Like (10[1])cochlear implants, these (10[2])devices can be used to mask external signals received during tinnitus. (10[1])For 10 points, name these devices (10[1])that amplify signals (10[2])entering the ears (10[1])of deaf (10[1])people. ■END■ (10[10])
