A sound level meter (also called sound pressure level meter (SPL)) is used for acoustic measurements. It is commonly a hand-held instrument with a microphone. The best type of microphone for sound level meters is the condenser microphone, which combines precision with stability and reliability. [1]

声级计（Sound Level Meter）或声压计是最基本的声学测量仪器，声压级 SPL（Sound Pressure Level）测量是其最基本的功能。 对于很多功能单一的声级计，人们也习惯称为“分贝仪”或“噪音计”等。 💡 声级计的应用场景非常广泛，包括噪声测量，音频与声学安装，室内和建筑声学，品质控制，航空航天，科研等。 声级计一般是手持式仪器，主要由传声器、前置放大器、信号处理器和显示器组成。 也可以简单看成由量测麦克风（传声器+前置放大器等元件）和主机（信号处理器+ …

A sound level meter (SLM) is a hand-held device that measures sound pressure levels by converting them from Pascals to decibels (dB), with applications in occupational noise monitoring, environmental noise assessment, and building acoustics.

Decibel Meter, TS-501A Sound Level Meter with 2.25” Backlight LCD Screen, Portable SPL Meter with A Weighted, Range 30-130dB, Data Hold, MAX/MIN, Use for Home, Noisy Neighbor, Factory - Orange

SPL sound pressure level is typically measured using a sound pressure level meter. The sound pressure level meter includes a microphone, processing section, and display. Sound pressure waves set a microphone membrane in movements, which are converted into electrical signals by the sound pressure level meter.

2024年5月28日 · Sound pressure level meters are designed to measure the pressure of sound waves as they travel through the air. The basic component of an SPL meter is the microphone, which captures sound waves and converts them into electrical signals.

A sound level meter is designed to respond to sound in the same way as the human ear and to give reproducible measurements of sound pressure levels (SPL).

2012年1月27日 · Packaged as a single-function handheld test device, SLMs are intended to be held at arm’s length during measurements (to reduce the effects of the body on the measurements) or secured to a tripod stand for more stability.

2016年8月17日 · The check mate series SPL (sound pressure level) meters, first introduced in early 2003, allow musicians, sound contractors, and others to measure SPL in decibels (dB). a decibel is defined as the unit for measuring relative loudness of a sound.
