Definition

1. Noun:
   • Sound wave: A wave of compression and rarefaction, by which sound is propagated in an elastic medium such as air. It is a physical phenomenon of sound transmission.

Usage Examples

• Noun:
  • Âm ba lan truyền trong nước nhanh hơn trong không khí. (Sound waves propagate faster in water than in air.)
  • Tai người có thể cảm nhận được những âm ba trong một dải tần số nhất định. (The human ear can perceive sound waves within a specific frequency range.)
  • Máy siêu âm hoạt động dựa trên nguyên lý phản xạ của âm ba. (Ultrasound machines operate on the principle of sound wave reflection.)

Advanced Usage

• Technical/Scientific Context: The term is primarily used in physics, acoustics, and engineering contexts to describe the physical propagation of sound.
  • Phân tích phổ của âm ba giúp xác định các đặc tính của nguồn âm. (Analyzing the spectrum of sound waves helps determine the characteristics of the sound source.)

Variants and Related Words

• Sóng âm: This is a more common and general synonym for "sound wave". "Âm ba" is a more technical or literary term.
  • Sóng âm thanh (Sound wave): Often used interchangeably.
• Âm thanh (Sound): Refers to the sensation or the physical phenomenon in a more general sense, not specifically the wave itself.
• Dao động âm (Acoustic oscillation): Refers to the vibration that creates the sound wave.

Synonyms

• Sóng âm: Sound wave.
• Sóng âm thanh: Sound wave.

Related Phrases/Compounds

• Sự lan truyền âm ba: Sound wave propagation.
• Tốc độ âm ba: Sound wave velocity.
• Phản xạ âm ba: Sound wave reflection.
• Khúc xạ âm ba: Sound wave refraction.

Notes on Usage

• Formality: "Âm ba" is a formal, technical term. In everyday conversation, "sóng âm" or simply "âm thanh" (depending on context) is more common.
• Scope: It specifically denotes the wave sound energy, not the sound perception itself. It is a term from wave physics.
• Figurative Use: In literary contexts, "âm ba" can sometimes be used metaphorically to mean "reverberations" or "echoes" (e.g., of an event or idea), though this is an extended meaning based on its core definition.
  • Âm ba của cuộc cách mạng vẫn còn vang vọng. (The reverberations of the revolution still echo.)
