On the Subject of Double Listening
“I don’t know the difference, is that arcade or casino?” “Yes.”
The module features a play button, a black, square submit button, and five single-bit displays along the bottom. Pressing the play button will play two sounds from the classic Listening module at the same time. The play button has a cooldown period of 3 seconds. Use the original Listening manual to obtain two five-character codes, each corresponding to one of the sounds.
Using the first row from Table A which applies, convert each character in each obtained code to a binary digit. Perform a bitwise XOR* operation on the two five-digit binary codes and submit the result using the displays at the bottom of the module. Submitting the wrong response will incur a strike and reset the module.
Table A
| Condition | Symbol | |||
|---|---|---|---|---|
| # | $ | & | * | |
| If the bomb has at least 3 batteries and at least one of the sounds was Beach or Waterfall | 0 | 0 | 1 | 1 |
| Otherwise, if the bomb has an empty port plate | 0 | 1 | 0 | 1 |
| Otherwise, if the last digit of the bomb’s serial number is odd | 1 | 0 | 1 | 0 |
| Otherwise | 1 | 1 | 0 | 0 |
NB: Some sounds have had their volume adjusted to prevent them from drowning others out.
*To perform a bitwise XOR operation, consider the digits of the two binary codes one position at a time. The result for each position is a 1 if the digits in the two codes at that position are both different. Otherwise, the result for that position is a 0.
