Sound level meter(or SPL) app is shows a decibel values by measure the environmental noise, displays measured dB values in various forms. you'll experience tidy graphic design with high frame by this smart sound meter app. Decibel meters also are referred to as sound level meters (decibel meters), noise detection, sound meters, noise detectors, and noise detectors. Decibel meter may be a noise detection software that uses mobile microphone to live the ambient noise decibel (dB). The current decibel size and curve are displayed during the method . With the decibel meter, you'll measure the present ring The background level of the environment is straightforward and straightforward to use. Functions: - The dashboard displays the present noise decibel value - Display min/aver/max/current decibel value - Display decibel size change chart - Auto decibel value calibrate - Display test time 11 Levels of Noise: 120dB: thunder 110dB: rock 'n' roll 100dB: train 90dB: factory 80dB: busy street 70dB: busy traffic 60dB: conversation 50dB: quiet library 40dB: quiet park 30dB: whisper 20dB: leaves fall Decibels: dB, dB(A), dBA, dB(C), dBV, dBm and dBi? What are they all? The decibel (dB) may be a logarithmic unit wont to measure sound level. it's also widely utilized in electronics, signals and communication. The dB may be a logarithmic way of describing a ratio. The ratio could also be power, instantaneous sound pressure , voltage or intensity or several other things. afterward we relate dB to the phon and to the sone, which measures loudness. What is a Sound level meter? A sound level meter is employed for acoustic (sound that travels through air) measurements. it's commonly a hand-held instrument with a microphone. the simplest sort of microphone for sound level meters is that the condenser microphone[1], which mixes precision with stability and reliability. The diaphragm of the microphone responds to changes in atmospheric pressure caused by sound waves. that's why the instrument is usually mentioned as a instantaneous sound pressure Level (SPL) Meter. This movement of the diaphragm, i.e. the instantaneous sound pressure deviation (pascal Pa), is converted into an electrical signal (volts V). While describing sound in terms of instantaneous sound pressure (Pascal) is feasible , a logarithmic conversion is typically applied and therefore the instantaneous sound pressure level is stated instead, with 0 dB SPL adequate to 20 micropascals. A microphone is distinguishable by the voltage value produced when a known, constant instantaneous sound pressure is applied. this is often referred to as the microphone sensitivity. The instrument must know the sensitivity of the actual microphone getting used . Using this information, the instrument is in a position to accurately convert the electrical signal back to a instantaneous sound pressure , and display the resulting instantaneous sound pressure level (decibels dB SPL). Sound level meters are commonly utilized in sound pollution studies for the quantification of various sorts of noise, especially for industrial, environmental, mining[2] and aircraft noise. the present international standard that specifies sound level meter functionality and performances is that the IEC 61672-1:2013. However, the reading from a sound level meter doesn't correlate well to human-perceived loudness, which is best measured by a loudness meter. Specific loudness may be a compressive nonlinearity and varies at certain levels and at certain frequencies.These metrics also can be calculated during a number of various ways Note: Microphones in most IOS devices are aligned to human voice. the utmost values are limited by the device. Very loud sounds(over ~90 dB) might not be recognized in most device. So please use it as just an auxiliary tools.

Verdict
The clearest difference is review sentiment: CodeBrew at 69% against Decibel Sound Meter's 0%. CodeBrew also leads on ads (none vs shown) and monetization model (free vs free with in-app purchases). Decibel Sound Meter's advantage is rating (4.8 vs 3.8). On price, ratings volume, update cadence and in-app purchases there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. Decibel Sound Meter sells 3 in-app purchases, starting at $0.99 per 7 days and CodeBrew sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.
Decibel Sound Meter holds the better App Store score, 4.8 against 3.8. Both are backed by a comparable volume of ratings — 4 and 9 respectively. Written reviews complicate that: 0% of Decibel Sound Meter's written reviews are positive against 69% of CodeBrew's, so the app with the better star average is not the one people write more warmly about.
Decibel Sound Meter ships an update every 4 months, CodeBrew every 3 months. The most recent releases landed on September 18, 2026 and July 6, 2026 respectively.
