• • • Decibel Ultra • • • - Would you like to know how loud the TV, music or the environment is? - Or your neighbour is too loud? With Decibel Ultra you know it exactly! - Decibel Ultra measures the volume and helps you figure out how big the noise level compared to reference values. - Calibrate with Decibel Ultra all your surround speakers to the same level. Decibel Ultra measure the sound pressure level (SPL) in dB professional frequency weightings: A, B, C, D ,Z (flat) and time weightings: Fast, Slow, Impulse. - Perfect to tune guitars. - Send the results quickly via email. - interested how loud you are? - Ultra-precise measurement of frequencies, a sine of 1000.0 Hz appears really as 1000.0 Hz! - Calibrated to the internal microphone, equipment enclosed headphones, MicW microphone or with line-in. Decibel Ultra is calibrated to standard 94dB at 0776 Vrms / 1000 Hz. Decibel Ultra was calibrated with a Class 1 Sound Level Meter and calibrator! From device to device, it may still be fluctuations around a few dB (2-3 dB). The app set the device into a special, best possible measurement mode. The automatic gain control (AGC) will turn off to get clean measurement without distort signals. On some older devices, the AGC can not turned off by software, it will then automatically corrected in the calculation. Depending on the unit generation, it varies how sensitive is the device. For example the current iOS devices e.g. iPhone 6 (plus) the internal microphone of an iOS device can not perform any measurement below 30 dB. Measurements below 40 dB with an external microphone or via the headphone jack supplied line output, are not possible with this current devices. The headset that came with the iOS device, cannot measure below about 44 dB. This is a limitation of the current device. But hey, 30 dB is already really sensitive! Highly recommended is the MicW i436. It has a very linear frequency response and dynamic, ideal for precise professional measurements. Continuous noise can be a potential hazard to your health! I would like to thank the company MicW Audio and Synthax GmbH for their kind support. Free version. The ad-free version is called "Decibel Ultra pro" here in the iTunes Store.
