Understanding Sound in Language Acquisition

Understanding Sound in Language Acquisition

Which loss high or low frequency will have the greater effect on comprehending spoken language and what will the implications for a preschooler, child of 6 to 9 years and adolescent.

Communication is mutlisensory,

Communication received is through our senses of smell, touch, taste, vision and hearing.

Two major acquisition of language

1) Imprinting: learning as a high rate to acquire information.

2) Critical periods: is the period of development.

Child Development.

· Very soon after birth infant learns to distinguish between speech sounds from other types of sound.

· 18 months old toddler can recognize and can use the phonemes of their language and can construct two-word phrases.

· 3.5 years old can construct nearly all the possible sentence types.

Physical Bases of Sound

Sound is carried as energy; transmission takes place from one molecule to the next by vibrating mediums.

Sound waves posses specific characteristics:

Frequency shows the number of completed wave cycles/unit of time.

One second frequency is expressed in Herts (Hz) meaning cycles/seconds.

High frequency sounds vibrate many more times/second.

Pitch is the distinguishing preceptor of higher-frequency sounds from lower frequencies.

Amplitude is the extent to which air particles move from their original resting place by the intensity of the sound waves.

Intensity is the overall amplitude of a sound.

All sounds are made of up complex sound waves.

Loudness in our perception of sound waves frequencies and duration of a sound.

Frequency effects in the processing of phonology, reading, spelling, formulaic language, language comprehension, grammaticality, sentence production, and syntax.

Sound and its biological Process

Vibration energy is what arrives in the ear and the brain receives this stimuli and in a complex process.

The outer ear, middle ear and the inner ear, are the pathways to collect and translate the vibration into electrical impulses for the brain.

This channel has the ability to
