MY VOCAB PRACTICE

1. I couldn't understand the lyrics of the song as the acoustics were terrible, making the words inaudible.
2. We rented a large auditorium as the lecturer was quite popular and a large number of people were expected.
3. The audience applauded out of a sense of duty in spite of the fact that the children's play was awful.
4. Aural aids can ameliorate one's hearing and often become necessary late in life.
