My Flashcards

Definition

Meaning

A unit of frequency equal to one thousand hertz (1000 Hz).

A measure of how many cycles per second occur in a periodic signal, such as radio waves or sound waves, scaled by one thousand.

Linguistics

Semantic Notes

Used primarily in electronics, telecommunications, acoustics, and computing. Not typically used in everyday conversation. Symbol: kHz.

Dialectal Variation

British vs American Usage

Differences

No significant lexical or usage differences between UK and US English.

Connotations

Technical, precise. No regional connotations.

Frequency

Equally infrequent in general speech in both regions, but standard in technical contexts globally.

Examples

By Part of Speech

adjective

British English

  • The kilohertz sampling rate

American English

  • A kilohertz frequency signal

Examples

By CEFR Level

A2
  • This radio station is on 95 kilohertz.
B1
  • Human hearing can detect sounds up to about 20 kilohertz.
B2
  • The engineer adjusted the transmitter to the correct kilohertz frequency for the emergency broadcast.
C1
  • High-resolution audio often uses a sampling rate of 96 kilohertz to capture ultrasonic harmonics.

Learning

Memory Aids

Mnemonic

Think 'kilo' (thousand) + 'hertz' (cycles per second). Like a kilogram is a thousand grams, a kilohertz is a thousand hertz.

Conceptual Metaphor

Frequency as a wave count (a 'kilohertz' is a 'thousand waves per second').

Watch out

Common Pitfalls

Translation Traps (for Russian speakers)

  • Direct transliteration is 'килогерц' (kilogerts), which is the correct term.
  • Avoid confusing 'hertz' (герц) with 'heart' (сердце).

Common Mistakes

  • Spelling as 'kiloherts' or 'killobertz'.
  • Incorrectly using it as a unit for speed or distance.
  • Pronouncing the 'hz' as separate letters instead of 'hertz'.

FAQ

Frequently Asked Questions

No, it is a technical term used primarily in engineering, physics, and audio fields.

One kilohertz (kHz) is equal to one thousand hertz (Hz). Hertz is the base unit.

Yes, the upper limit of human hearing for most adults is between 15-20 kilohertz.

It is both singular and plural (like 'hertz'). You say 'one kilohertz' and 'ten kilohertz'.
