He also hears many different sounds around him, and as he grows older, he begins to imitate them. By twelve months he can produce a recognizable word or two, and clearly understands a good deal of what is said to him. Vowels and labials are easiest to say, and gutturals and diphthongs the most difficult. He needs much practice in the use of his speech organs before he can produce the required sounds at will, and it is not until the second year of his life that he seems prepared to spend time and energy on the business of learning to talk. The baby seems to delight in noise that is, in the noise makes himself, banging spoons, throwing bricks, waving bells and knocking the fire-irons about, he is however, disturbed by very loud noises, especially if they are unfamiliar, and if he is not reassured by his mother’s presence.
He responds better to quiet, gentle voices than to loud, sharp ones. He is usually responsive to music and rhythm. He will listen to a tune on the piano or the radio with great pleasure, and will even beat time. He enjoys movement and is attracted by anything that moves.
