About

This application measures acoustic resonance and spectrum using an iPhone's microphone and earphone. It outputs specific frequencies to an earphone and measures the volume on the object with the microphone, displaying results on a frequency characteristic graph. It's ideal for demonstrating phenomena like Helmholtz and Air Column Resonance.

✓Acoustic measurement via earphone microphone
✓Frequency sweeping from start to end
✓Displays frequency characteristic graph
✓Measures Helmholtz Resonance
✓Measures Air Column Resonance
✓Adjustable volume before measurement
✓Cursor for Hz and dB values

Very good

I have tested this app. It is reliable and friendly to check resonance. You need a high quality earphone with high quality mic.

This has great potential

It works fine on my iPad Pro 9.7” … although a proper iPad version would be nice to have.
.
My only concern, so far, is that the loud ticking [metronome?] seems likely to affect the results … Is it possible to mute this ?
.
Thanks for what appears to be a great little App.

FAQ

What is ResoSearch used for?

ResoSearch is used to perform acoustic measurements and analyze spectrums. It helps users visualize resonance phenomena like Helmholtz and Air Column Resonance by measuring sound frequencies.

How does ResoSearch measure acoustic resonance?

It uses the iPhone's earphone with a microphone. A specific frequency is output from the earphone to the object, and the microphone measures the resulting volume, displaying it on a frequency characteristic graph.

What types of resonance can ResoSearch measure?

ResoSearch can measure Helmholtz Resonance, typically in narrow-mouth bottles, and Air Column Resonance, by wrapping objects like posters into cylinders.

What devices does ResoSearch support?

ResoSearch is supported on iPhone and iPod devices. It was last updated on June 22, 2017, with version 1.2.

Is ResoSearch suitable for educational purposes?

Yes, ResoSearch is designed for educational use, allowing users to observe and understand acoustic resonance phenomena in a practical, hands-on way.

Can ResoSearch be used without earphones?

While measurement can be attempted with the built-in speaker and microphone, the iPhone's own acoustic characteristics can affect accuracy. Using external speakers is possible but potentially dangerous due to loud noise.

What is the age rating for ResoSearch?

ResoSearch has an age rating of 4+, making it suitable for a wide range of users, including younger learners under supervision.

Does ResoSearch have ads?

No, ResoSearch does not contain advertisements. It is a free application without any ads.
