Try using findpeaks from the Signal Processing Toolbox. You can specify minimum peak height, and after getting the results, you can throw away the peaks that exceed your upper bound.
How to search for peaks in a signal?

I made some measurements of vibration and I have applied the FFT to view the signal spectrum, I want to make a "peak search" so that putting a condition, the program throws me values ??greater than the setpoint. For example my frequency range from 0 Hz to 1 kHz and amplitude of the spectrum ranges from 0 to 5 mm / s, I want to know how many peaks are between 1.12 mm / s and 2.3 mm / s, and at what frequencies correspond these values???
