Actually, this isn't necessarily wrong.
I used a website to try to play back the sound of this spectogram. (As you probably know, a spectogram shows frequency over time.)
Here is the website I used: https://nsspot.herokuapp.com/imagetoaudio/
At first it didn't sound like anything. But then I found that the site plays black and white spectograms more easily, so I made your original image black and white and I was able to hear a little bit of sound. I have attached the B&W version that I made. On the website, I made sure to bring the "length" value to something like 20, and the "density" value to 1. I also used the "selected area" option, and cropped out most of the top of the image where there is no data, so the overall max frequency levels are higher throughout the entire sample.
However, I was never able to get any kind of sound without a large amount of distortion. I don't think this has anything to do with your image. I tried making a few other spectograms myself, but never was able to hear any of the original audio back. I think that the site that I found just doesn't work quite right. Or I don't know how to use it.
