Practice Listening: Fill in the Blanks (Type In) ID: #33695 Medium Auditory sensitivity
Instructions ›
You will hear a recording. Type the missing words in each blank.
* Fill in the missing words into the blank fields
Have  you  ever  wanted  to  turn  down  the  volume  at  a  deafening    or  noisy  bar?  Envy  the  whale:  a  new  study  finds  that  toothed  whales  can  reduce  their  own  auditory  sensitivity  when  they  expect  a  loud  sound.  The  work  is  presented  at  this  week's  Acoustics  2012  meeting.  Whales  and  dolphins  rely  on  their  responsive  hearing  to  interpret  returning  echolocation  clicks.  Previous  research  suggested  that  these  marine  mammals  could  dull  their  hearing  before  uttering  outgoing  echolocation  ,  which  are  very  loud.  Could  they  use  the  same  coping  mechanism  for    noises?  To  find  out,  researchers  trained  a  false  killer  whale  that  a  loud  noise  would  always  follow  a  brief  warning  .  Then,  they  attached  suction  cup  sensors  to  the  outside  of  the  whale's  head  and  played  the  signal.  The  sensors    brainwaves  that  indicated  the  whale  did  reduce  its  hearing  sensitivity  in  expectation  of  a  clamour.  The  researchers  hope  to  test  other  species  as  well.  Loud  noises  from  ships  can  disturb  whales.  To  accommodate    life,  perhaps  vessels  could  emit  signals  before  making  a  ruckus,  warning  whales  to  tune  us.

Correct answer: concert

Explanation: The speaker says "deafening concert or noisy". It comes after "deafening", so you need a word for an event or thing.

Meaning: "concert" means a musical show.

Wrong options:

  • concet: It leaves out the "r". Write "concert". Only the exact spelling gets the mark.
  • concerts: "concerts" has an extra "s" at the end. The speaker says "concert", with no "s".
Correct answer: clicks

Explanation: You hear "outgoing echolocation clicks, which". The sentence needs more than one, so the word ends in s.

Meaning: "clicks" means short sound pulses whales use to find things.

Wrong options:

  • click: "click" has no "s" at the end. The speaker says "clicks", so write the "s".
  • cliks: It leaves out the "c". Write "clicks". Only the exact spelling gets the mark.
Correct answer: external

Explanation: Listen for "same coping mechanism for external noises". It comes before "noises", so you need a word meaning outside, ends in al.

Meaning: "external" means outside or from the outside.

Wrong options:

  • exernal: It leaves out the "t". The right spelling is "external". Every letter must be correct to get the mark.
  • internal: Internal means inside, not outside, so it does not fit here.
Correct answer: signal

Explanation: On the recording you hear "brief warning signal. Then, they". It comes after "warning", so you need a word for a short sound or sign.

Meaning: "signal" means a short sound or sign used to warn.

Wrong options:

  • sigal: It leaves out the "n". Write "signal". Only the exact spelling gets the mark.
Correct answer: measured

Explanation: Listen again to "The sensors measured brainwaves that". This already happened, so the word ends in ed.

Meaning: "measured" means recorded or took readings.

Wrong options:

  • mesured: It leaves out the "a". The right spelling is "measured". Every letter must be correct to get the mark.
  • measure: "measure" is missing the ending. The speaker says "measured", with "d" at the end.
Correct answer: marine

Explanation: Here you hear "To accommodate marine life, perhaps". It comes before "life", so you need a word for sea animals.

Meaning: "marine" means of the sea or sea animals and plants.

Wrong options:

  • marinne: It adds an extra "n". Check the letters: "marine". A small spelling mistake loses the mark.
