In employing these results, it must be considered that data, particularly from stranded wild animals, older individuals, or high noise areas, may reflect abnormal hearing. Case studies demonstrate pinnipeds sustain a wide range of conditions that may impair hearing. Approximately 20 % of stranded seals have ear infections which if undetected and untreated may lead to septicemia.
