It turns your iOS device into a professional sound level meter, precisely measures the sound pressure level (SPL) all around you. This extremely useful and beautiful tool will not only be a great tool for many uses but also bring you a lot of fun. Have you wondered how quiet is your room or how loud is a rock concert or sport event? "Decibel X" will help you answer all of those. WHAT MAKE IT GREAT AND STAND OUT FROM OTHER APPS: - Trusted accuracy: the app is tested and pre calibrated for all Apple devices. The precision is matching with real SPL devices - Apple Watch support: see noise level right from your wrist - Health App integration: export noise levels directly into Health app - Frequency weighting filters: ITU-R 468, A, B, C, Z - Powerful, smart history data management: + Recording data can be saved into a list of history records for future access and analysis + Each record can be exported as hi-res PNG graph or CSV text via sharing services + iCloud support which synchronize all history records across your Apple devices + Fullscreen mode to give overview the whole history of an record - Dosimeter with NIOSH, OSHA standards - Powerful calibration: Linear, Octave 1/1, 1/3, Load/save profile - FFT and BAR graphs to display real time FFT. Those are very useful for frequency analysis and musical tests. Real time predominant frequency is also displayed. - InstaDecibel to capture your dB report overlaid on photos and easily shared via popular social networks (Facebook, Instagram, Messages, etc.). - Support Live Activity, Dynamic Island - Support both Portrait and Landscape layouts - Beautiful, intuitive and carefully crafted UI design. Themes: LIGHT, DARK and CLASSIC OTHER GREAT FEATURES: - Standard time weightings (Response Time): SLOW (500 milliseconds), FAST (200 milliseconds) AND IMPULSE (50 milliseconds) - MIC Gain Offset from -50 dB to 50 dB - Standard measurement range from 30 dBA up to 130 dBA - HISTO graph for plotted history of the recorded values - WAVE graph with 2 display modes: Rolling & Buffer - SPECTROGRAPH - Real time scale level chart - Display Current, Average/Leq, and Max values with both nice and clear digital and analog layouts - Quick reference text to help you compare with real-life examples NOTES: - Please do not expect a quiet room reading will be 0 dBA. The range 30-130 dBA is the standard usable range and an average quiet room will be about 30 dBA. - Although all devices are pre-calibrated, custom calibration is suggested for serious purposes requiring higher precision and accuracy. You will need a real external device or calibrated sound meter as a reference, then adjust the trimming calibration until the reading matches with the reference. * Privacy Policy: * EULA: ## Decibel X Screenshots - [Screenshot 1](https://is1-ssl.mzstatic.com/image/thumb/Purple126/v4/a1/de/82/a1de8244-983c-832c-9964-d521321d98aa/7429d385-fdad-4f59-b102-bd95fa6d3eab_65in_en_01.jpg/1242x2688.png) - [Screenshot 2](https://is1-ssl.mzstatic.com/image/thumb/Purple126/v4/f0/3b/72/f03b7228-91be-360c-d455-8148770a2df6/749e29ce-af10-4ed0-8dd9-e499d2b3ac4a_65in_en_02.jpg/1242x2688.png) - [Screenshot 3](https://is1-ssl.mzstatic.com/image/thumb/Purple116/v4/4e/84/52/4e84525e-4d1b-0051-f7cb-98c85bd59722/55cfd97f-1aac-4da2-976e-0e28fc0c8987_65in_en_03.jpg/1242x2688.png) - [Screenshot 4](https://is1-ssl.mzstatic.com/image/thumb/Purple126/v4/bb/ef/d5/bbefd569-ff1f-4d19-6b68-569ede62921f/4245248e-ce7c-449a-856f-c8d3470d5f08_65in_en_04.jpg/1242x2688.png) - [Screenshot 5](https://is1-ssl.mzstatic.com/image/thumb/Purple126/v4/c3/b2/fc/c3b2fcca-bc60-b76c-49ce-2604e79126b6/ff61b527-677e-4a5f-b906-b69af3db43e3_65in_en_05.jpg/1242x2688.png) - [Screenshot 6](https://is1-ssl.mzstatic.com/image/thumb/Purple126/v4/38/cf/de/38cfde03-ea9a-236a-8d9d-d52c575b1dc4/6876cc89-01c9-4035-8648-44b85587c529_65in_en_06.jpg/1242x2688.png) - [Screenshot 7](https://is1-ssl.mzstatic.com/image/thumb/Purple116/v4/55/30/64/553064a8-e94a-5aea-00db-3b58b63bf4a2/15239e29-8d7c-424b-baf3-0427672e8805_65in_en_08.jpg/1242x2688.png) - [Screenshot 8](https://is1-ssl.mzstatic.com/image/thumb/Purple116/v4/85/c2/f1/85c2f154-4356-4562-1110-86c596dc1b0c/8de486ab-97f7-410e-8d90-9bdf82184cc4_65in_en_09.jpg/1242x2688.png) ## Decibel X Rating Breakdown in United States - 5 stars: 129,579 (80%) - 4 stars: 20,439 (13%) - 3 stars: 5,699 (4%) - 2 stars: 1,808 (1%) - 1 stars: 5,048 (3%) ## Decibel X Reviews in United States ### *---- "Talking as loud as a motorcycle or food blender?!" This thing is so inaccurate. All I have to do is talk and it says I'm as loud as a food blender or motorcycle. -- Jesse S. 3, 2024-12-20 ### ***** "Wonderful" I use it all the time -- Ajay Phoenix, 2024-12-17 ### ***** "Get this one" This is the Real Deal. FOH for 20 years. I use this every night at my venue. Don’t waste your time with cheap / free ones, trust me. Get it! -- Tate ML, 2024-12-15 ### ***** "Great handy tool" Easy and on when app opens. Use it to check exhaust noise levels on motorcycles. -- Curly5962, 2024-12-13 ### **--- "Meter Brightness" While familiarizing myself to this App I touched the dark screen button. I was disappointed that I could not go back to the light screen unless I went to premium. -- CRS1000, 2024-12-12 ### ***** "Very accurate" I have had this app for years. People are always curious about the decibel levels. The free upgrades are always great. -- Guegkh45$&, 2024-12-11 ### ***** "Noise detector" I recommend this app for detecting loud noise. -- Starbuckskid037, 2024-12-08 ### ***** "Great tool" Helps me monitor my environment to better protect my hearing -- TomC67.eth, 2024-12-08 ### ***** "Taste good" This app tasted great -- edit man1428, 2024-12-04 ### ***** "It’s God’s gift" I would say this app is the single most valuable app I have downloaded from Apple. Sounds are hard to measure even if exposure to high level of noise can PERMANENTLY damage ears. This is a blessing for humanity and God bless you! -- Criticial user, 2024-11-23 [View all Decibel X reviews and detailed analytics on AppTail](https://app.apptail.io/signup?utm_campaign=ai-crawl&utm_content=reviews) ## Decibel X In-App Purchases | Item | Price | |------|-------| | Data Export | $2.99 | | Annual Membership | $44.99 | | Weekly Membership | $1.99 | | Monthly Membership | $4.99 | | ITU-R 468, A, B, C Weightings | $1.99 | ## Decibel X Store Rankings | Chart | Country | Category | Rank | |-------|---------|----------|------| | Top Grossing | Finland | Utilities | #70 | | Top Free | Switzerland | Utilities | #107 | | Top Free | Germany | Utilities | #114 | | Top Free | Netherlands | Utilities | #128 | | Top Free | South Korea | Utilities | #133 | | Top Free | Belgium | Utilities | #141 | | Top Free | Australia | Utilities | #155 | | Top Free | Hungary | Utilities | #157 | | Top Free | Canada | Utilities | #175 | | Top Free | France | Utilities | #175 | | Top Free | Spain | Utilities | #179 | | Top Free | Japan | Utilities | #186 | | Top Free | Poland | Utilities | #196 | | Top Free | Singapore | Utilities | #214 | | Top Free | United States | Utilities | #216 | | Top Free | Austria | Utilities | #219 | | Top Free | United Kingdom | Utilities | #226 | | Top Free | Ireland | Utilities | #240 | | Top Free | Hong Kong SAR China | Utilities | #244 | ## Decibel X Discovered Keywords -
