As concerns for noise impacts continue, more species and individuals are being tested to determine hearing ranges and peak sensitivities. 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.
