noises at that level can frighten and confuse whales。a team of American and Canadian scientists discovered that louder noises can seriously injure some animals .the research team found that powerful under water explosions were causing whales in the area to lose their hearing .this seriously affected the whales ab Exchange information and find their way。some of the whales even died。the explosions had caused their ears to bleed and become infected .many researchers whose work depends on ocean sounds are against a limit of one hundred and twenty decibels。they say such a limit would mean end to
