Decibel Meter

A decibel meter, also known as a sound level meter or SPL meter, is a device used to measure the intensity or loudness of sound in decibels (dB). It consists of a microphone that captures sound waves, converts them into electrical signals, and then analyzes and displays the sound level readings.

Decibel meters are commonly used for various purposes, including occupational safety, environmental noise monitoring, and audio engineering. They provide valuable information about sound levels to ensure compliance with regulations, assess potential health risks, and optimize audio quality.

Decibel meters typically display the instantaneous sound level as well as various statistical parameters such as maximum, minimum, and average readings. Some advanced models may also offer octave band analysis, frequency weighting options (e.g., A, C, or Z), and time weighting options (e.g., fast or slow response).

Users can position the decibel meter at the desired location to measure sound levels accurately. The device captures the sound, analyzes it, and presents the results on a digital display. The readings are typically shown in decibels, which provide a logarithmic representation of sound intensity relative to a reference level.

Decibel meters are essential tools for assessing noise pollution, ensuring workplace safety, conducting acoustic measurements, and optimizing audio settings in various settings.

分貝計，也稱為聲級計或 SPL 計，是一種用於測量聲音強度或響度（以分貝 (dB) 為單位）的設備。 它由一個麥克風組成，捕獲聲波，將其轉換為電信號，然後分析並顯示聲級讀數。

分貝計通常用於多種用途，包括職業安全、環境噪音監測和音訊工程。 它們提供有關聲級的寶貴信息，以確保遵守法規、評估潛在的健康風險並優化音訊品質。

分貝計通常顯示瞬時聲級以及各種統計參數，例如最大、最小和平均讀數。 一些進階模型還可能提供倍頻程分析、頻率加權選項（例如 A、C 或 Z）和時間加權選項（例如快速或慢速響應）。

使用者可以將分貝計放置在所需位置以準確測量聲級。 該設備捕獲聲音，對其進行分析，並將結果顯示在數位顯示器上。 讀數通常以分貝為單位顯示，它提供聲音強度相對於參考水平的對數表示。

分貝計是評估噪音污染、確保工作場所安全、進行聲學測量以及優化各種環境下的音訊設定的重要工具。
