SmarterNoise vs Noise Recorder

SmarterNoise measures sound level, records video and audio and informs about noise SmarterNoise is a premium sound level meter app featuring several unique functions. SmarterNoise measures sound levels in video and audio modes, records video and sound, and informs you about the risks of noise exposure. In addition, SmarterNoise includes a camera, measurement location, and easy sharing, all for free. From the archive you can view the video and audio files you've saved on your phone. With SmarterNoise you take sound level and noise measuring to a new level never available before. SmarterNoise features smart icons that react to the measured sound levels based on current research results focusing on the health and the adverse effects of noise pollution. With the SmarterNoise icons you easily understand how hearing, cognitive performance, and health may be affected by different levels of noise exposure. The awareness of harmful noise is increasing globally, and is considered a versatile risk factor for well-being and health, especially in noise polluted urban environments.

Because the decibel scale is logarithmic, a sound with an intensity that is twice that of a reference sound corresponds to an increase of about 3 decibels. The reference point of 0 decibel is set at the intensity of the least perceptible sound, the threshold of hearing. On such a scale a 10-decibel sound is 10 times the intensity of the reference sound. Highlighting this is important as already a difference of a few decibels makes a noticeable difference in how noise is perceived. Leq is an average value describing the total sound energy over a period of time. It is however common practice to measure sound levels using A-weighting, which attenuates low and high frequencies that the average person cannot hear. In this case Leq is written LAeq. LAeq is a formulated average which emphasizes higher sound peaks, and is one of the most common measurements used by professionals to measure noise. All averages in SmarterNoise are measured in LAeq. Health effects of noise are often measured in Lden. Lden measures the average sound level over a 24 hour period, with a penalty of 5 dB added for the evening hours between 19:00 and 22:00, and a penalty of 10 dB added for the nighttime hours between 22:00 and 07:00. Increased health risks have been observed during long term exposure, which highlights the need to consider the full average sound energy over a longer period, not only temporary averages or noise peaks. About noise According to the findings of the World Health Organization (WHO), noise is the second largest environmental cause of health problems, after the impact of air quality. While environmental awareness in general has increased, the burden of noise has not yet been realized by the general public. People especially in urban environments are subjected to noise daily and nightly, at home and at work. Noise pollution has increased over the years due to increased traffic and air travel, urbanization, and industrial noise exposure. Because of the complex and frequent issue of everyday noise, we developed SmarterNoise in order for people to understand noise better.

Measure environmental noise, record audio and video, and create PDF reports you can review and share. Noise Recorder - Pro combines a decibel meter, audio and video recording, and shareable reports. Keep a record of noise at home, at work or in other everyday settings, then revisit the sound and images whenever you need to. MEASURE AND RECORD • See current, minimum, average, and maximum decibel readings. • Record audio, or capture video with decibel readings and timestamps overlaid. • Inspect sound-level changes on charts with precise point selection, zooming and panning. REVIEW AND SHARE • Browse your recording history, preview saved videos with thumbnails, and play back audio and video. • Add notes to remember the context of each recording. • Review daily summaries of your saved recordings, including average and maximum readings, in the noise calendar and monthly charts. • Find saved recordings by note, decibel range or date. • Export PDF reports, share audio files, and save recorded videos to Photos. • Change the app language in Settings and see the interface update immediately. • Measurements and recordings are saved locally on your device. No app account is required. FREE AND PRO The free version includes 3 recordings per day, up to 15 seconds each. Pro removes the daily recording limit and the time limit for individual audio and video recordings. Actual recording duration depends on the storage available on your device. Choose a monthly subscription for Pro access while your subscription is active, or make a one-time purchase for lifetime Pro access. Both options offer the same Pro recording benefits. Readings are estimates and may vary with your device and surroundings. The app does not replace a calibrated sound level meter.
