SoundJaw Boosts iPad 2 Volume to Maximum Levels

Initially, I was quite skeptical about the SoundJaw, a modestly priced $20 gadget, which was previously featured as one of our Kickstarter entries and conceived by Matt McLachlan from Colorado. This clever device attaches to the base of an iPad 2, right over the speaker openings, and redirects the sound towards the user, effectively amplifying the audio output. I’m pleased to report that my initial doubts were unfounded, as the SoundJaw significantly boosts the sound volume from the iPad 2.

In an effort to objectively evaluate the SoundJaw, I acquired the Decibel Meter Pro app for $0.99 from Performance Audio LLC and installed it on my iPhone 4.

I was curious to compare the maximum loudness of a track played on my iPad 2, measuring the decibel levels with and without the SoundJaw in place. To ensure accuracy, I positioned the microphone consistently in both tests using a Glif mount and a tripod.

With the SoundJaw attached and the iPad 2 set to a medium volume, the peak sound level reached 68 dB, whereas it was 65 dB without the device. Subjectively, the difference wasn’t noticeable to me.

However, turning the volume to maximum made the difference more apparent: 79 dB with the SoundJaw versus 75 dB without it, and it was clear to me that the SoundJaw made the iPad sound louder.

Some might argue that a 3 or 4 dB difference isn’t significant. However, it’s important to understand that decibels are a logarithmic measure. Without delving into the complexities of psychoacoustics, perceived loudness, and Sound Pressure Level, it’s sufficient to say that a 3 dB change is just noticeable, whereas a 4 dB increase is definitely more perceptible.
