Good-Ear is a website run by musician Martin Schoeberl. It provides a means of listening to a tone "played" on an acoustic piano. You can alter the instrument being used. Other choices you can click on include the Rhodes piano which as an artificial, almost "squeeky" piano synthesizer sound. There is also violin which has a very artificial string sound. The guitar and electric piano choices have a more natural sound quality.
There are various combinations of notes that you can test yourself on. If you want to test yourself on intervals and are new to ear training, you can click on the "Beginner" link and then click on simple chords. A media player bar will appear in the middle of the screen and an interval will be played. Choices below the bar include Prime, major 3rd and minor 3rd, to name a few options. Click on one of these choices to see if you can identify the interval. A positive or negative response will appear above the media bar. But the actual note that you should have chosen will not be given. You can retry if you guessed incorrectly.
You can also test yourself on scales, chords and jazz chords. For those with perfect pitch, you can test yourself on how well you naturally hear notes. The notes are played one at a time and you can choose the correct one by clicking on a note name-like D, C, A-below the media windows bar.
Calling itself the Original Online Ear Trainer, Big Ears by Michael Ossman provides intervals that listeners can test themselves with. By clicking on the Big Ears icon, you can hear an interval being played. Note that the sound produced is an artificial synthesizer piano sound.
After clicking on the icon, click on one of the gray bars below the ears icon and message box to see if you know can correctly identify the interval. These gray bars are labeled with a P1, for perfect unison, P11 for perfect eleventh, M3 for major 3rd and m3, for minor 3rd, among other intervals. Click on the small icon below ear gray interval bar to hear the sound of that interval.
As this website only tests intervals it may be helpful to those interested in identifying single notes or different types of chords.
At Train Ear, there is a picture of a piano keyboard on which you can click to hear the sound of various notes.

Click on a new note while your eyes are closed to continue testing yourself.
You can also click "Play" and hear an interval being played. Click "Repeat" if you need to hear the same interval again. Note that if you click "Play" again, a new interval will be heard.
Next to these buttons is a list of songs. Click on the song you think matches the first two notes that were played. A song button will then appear. Click on this new button to get an answer as to whether you were right in your choice. The answer is located under the "Feedback" bar.
