It will show how loud sounds need to be at different frequencies for you to hear them. The audiogram shows the type, degree, and configuration of hearing loss. When you hear a sound during a hearing test, you raise your hand or push a button. Recall that controlling the pitch of the blade and speed of the generator are the most effective methods to adjust output power. The following control strategies use pitch and generator speed control to manage turbine functionality throughout the power curve: fixed-speed fixed-pitch, fixed-speed variable-pitch, variable-speed fixed-pitch, and variable-speed variable-pitch.
The test starts with a grid sensitivity of 1200 cents. That is the grid consists of only 1 column. That means: to pass the test you only have to click in the correct row, in which the played note was played. After you have passed 10 questions, the test continues with a grid sensitivity of 600 cents. Meaning the grid consists now of 2 columns.
Each time you have answered 10 questions the grid sensitivity decreases and the number of clickable columns increases. Therefore the difficulty increases you must listen more carefully to figure out the destination note - and thus leads to longer answer times.
The Pitch Grid Test may look like an absolute pitch test. However, it is a relative pitch test. The last played tone is highlighted on the grid and marks your reference tone for the next question.
Since you do not want to test grid sensitivities that you have already mastered, the Pitch Grid Test allows you to select the starting grid sensitivity for the test.
If you fail to answer the ten questions for a given grid sensitivity, then the test stops. Your relative pitch score is then calculated from the last past grid sensitivity and the maximum time you needed to answer a question.
To assess your relative pitch abilities, the answering-speed is crucial. Therefore, the answering time is also incorporated in the relative pitch indicator.

Includes 1µm, 10µm and 100µm pitch. The Pelcotec™ G-1 calibration specimen with a 1µm pitch grid is very useful for magnification calibration or image distortion check in the 100x to 10,000x magnification range. Can be used for SEM, Auger, Sims, FIB, and LM (reflected light). Three pitch sizes are available for these packages: 1.0 mm, 0.8 mm, and 0.5 mm. In general, as the pitch size decreases, the challenges for PCB routing increase as there is less room to route traces and vias between package balls. This guide illus trates various methods for successful design regardless of pitch size.
