Some of the more common ototoxic drugs include salicylates (aspirin) in large quantities, drugs used in chemotherapy treatments and aminoglycosides, a type of antibiotics. The difference in pitch stems from the oscillation, or the regular back and forth of the sound waves that emanate from those two sources. Concurrent exposure to ototoxic substances, such as solvents and heavy metals, may increase the damage potential of noise.7 Once exposure to damaging noise levels is discontinued, further significant progression of hearing loss stops.

Examples of "high-frequency" sounds are a bird chirping, a whistle, and the "s" sound in "sun." Loudness or Intensity Each line from top to bottom shows how loud the sound is in decibels, or dB. Noise can be described in terms of intensity (perceived as loudness) and frequency (perceived as pitch). Compare that to a dog's bark, which measures at about 1,000 Hz.
