The quicker you act, the higher chance there is for a full recovery. <\/p>\n\n\n\n<h2 class=\"wp-block-heading\">What Symptoms Do Those with SSD Experience?<\/h2>\n\n\n\n<p>Patients with SSD find understanding speech in the presence of background noise especially problematic and have great difficulty localizing sound (recognizing the location or origin of a sound source). Sound localization depends on subtle hearing cues from two ears; removing one from the equation confuses the brain.<\/p>\n\n\n\n<p>Many people also report experiencing a sensation known as the \u201c<a href=\"https:\/\/www.audiologyonline.com\/articles\/understanding-single-sided-deafness-evaluation-6829\" data-type=\"URL\" data-id=\"https:\/\/www.audiologyonline.com\/articles\/understanding-single-sided-deafness-evaluation-6829\" target=\"_blank\" rel=\"noreferrer noopener\">head shadow<\/a>\u201d effect. High frequency sound waves do not move around objects, so they never reach the good ear as the head gets in the way. This frequency loss prevents those with SSD from hearing&nbsp;<em>s<\/em>&nbsp;or&nbsp;<em>t<\/em>&nbsp;sounds.<\/p>\n\n\n\n<p>Other symptoms include:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Anxiety<\/li>\n\n\n\n<li>Stress<\/li>\n\n\n\n<li>Social isolation<\/li>\n\n\n\n<li>Dizziness<\/li>\n\n\n\n<li>Difficulty paying attention<\/li>\n\n\n\n<li>Trouble speaking loudly<\/li>\n<\/ul>\n\n\n\n<h2 class=\"wp-block-heading\">How is SSD Diagnosed?<\/h2>\n\n\n\n<p>In order to diagnose your type of loss, your Audiologist will review your symptoms and medical history before completing a physical exam. Your doctor will then complete a comprehensive hearing exam. These tests are used to determine your type and degree of hearing loss.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Treatments for SSD<\/h2>\n\n\n\n<p>While there is no cure for single sided deafness, options exist to help you cope with unilateral hearing.
