Question

Assertion: Larynx is called sound box. Reason: Larynx helps in production of sound.

Short answer

Yes, the assertion (Larynx is called sound box) is correct, and the reason (Larynx helps in production of sound) accurately justifies it.

Step-by-step solution

Analyze Assertion

Understanding the term 'Larynx' is essential to verify the given assertion. Larynx, also known as voice box, situated at the top of the windpipe, is an organ involved in breathing, producing sound, and protecting the trachea against food aspiration. So, referring it to as a 'sound box' is valid as it plays a crucial role in sound production.

Analyze Reason

This step involves understanding whether the given reason, 'Larynx helps in production of sound' is valid or not. The larynx houses the vocal cords, and manipulates pitch and volume, which is essential for phonation, beefing up the statement that 'Larynx helps in the production of sound'.

Combine Assertion and Reason

In this step, databinding needs to be made on whether the reason correctly justifies the assertion. Given the roles of the larynx in producing sound as explained in previous steps, it is correct that the larynx is often referred to as the 'sound box'. The given reason correctly justifies the assertion

Key concepts

Sound production

Sound production is a fascinating process that occurs in living organisms. The larynx, often referred to as the 'sound box', plays a vital role in this process. It is involved in generating sound waves by manipulating air as it passes through the vocal cords. When we speak or sing, the air from the lungs is pushed through the larynx causing the vocal cords to vibrate. These vibrations are what produce sound. The way these vibrations occur can change the pitch, tone, and volume of the sound, making it possible to produce a wide variety of sounds and languages.
Different elements such as the tension of the vocal cords and the force of the airflow affect the sound. This intricate process helps us communicate effectively with one another. Whether it’s whispering softly or shouting loudly, it all boils down to the ingenious sound-producing function of the larynx.

Voice box

The larynx is commonly known as the 'voice box'. This is because it acts as the primary organ responsible for voice production. Positioned at the top of the trachea, it not only produces sound but also plays a protective role by ensuring food and liquid do not enter the airways.
The term 'voice box' comes from the fact that the larynx houses the vocal cords, which are essential for generating the sounds we associate with the voice.

• It takes part in regulating airflow during breathing.
• It manages the opening and closing of the airways.
• It protects the trachea against food aspiration.

These important functions solidify its nickname as the 'voice box.'

Phonation

Phonation is the scientific term for the process by which the vocal cords produce sound. It involves several complex actions that transform simple breath into articulate sound. During phonation, the vocal cords come together and vibrate as air passes through them. This is how the basic raw sound is created. Phonation can be controlled to produce different pitches, volumes, and qualities of sound.
The muscles around the larynx adjust the tension and length of the vocal cords to alter the sound produced.

• For higher pitches, the cords are stretched tighter.
• For lower pitches, they are relaxed.
• Volume is controlled by the force of the air passing through the cords.

Mastery of phonation is essential for talking, singing, and any verbal communication.

Vocal cords

Vocal cords, or vocal folds, are key to sound production in the larynx. Positioned within the larynx, they are flexible bands of muscle that can tighten or loosen to vary sound characteristics. When air from the lungs is forced through them, it causes them to vibrate, producing sound waves.
Depending on how open or closed the vocal cords are, they can produce vastly different sounds.

• Loose vocal cords allow deep sounds.
• Tight vocal cords produce high-pitched sounds.
• The amount of air passing through affects loudness.

These cords play an instrumental role in our ability to speak, sing, and make different noises, highlighting their significance in everyday communication.
