Empty-room recordings may be collected once per day, where a single empty-room recording may be shared between multiple subjects and/or sessions (see [Example 1](#example-1)).
Empty-room recordings can also be collected for each individual experimental session (see [Example 2](#example-2)).

In the case of empty-room recordings being associated with multiple subjects and/or sessions, it is RECOMMENDED to store the empty-room recording inside a subject directory named `sub-emptyroom`.
In the case of empty-room recordings being associated with multiple subjects and/or sessions ([Example 1](#example-1)), it is RECOMMENDED to store the empty-room recording inside a subject directory named `sub-emptyroom`.
If a [`session-<label>`](../appendices/entities.md#ses) entity is present, its label SHOULD be the date of the empty-room recording in the format `YYYYMMDD`, that is `ses-YYYYMMDD`.
The `scans.tsv` file containing the date and time of the acquisition SHOULD also be included.
The rationale is that this naming scheme will allow users to easily retrieve the empty-room recording that best matches a particular experimental session, based on date and time of the recording.
It should be possible to query empty-room recordings just like usual subject recordings, hence all metadata sidecar files (such as the `channels.tsv`) file SHOULD be present as well.

In the case of empty-room recordings being collected for the individual experimental session, it is recommended to store the empty-room recording along with that subject and session.
In the case of empty-room recordings being collected for the individual experimental session ([Example 2](#example-2)), it is RECOMMENDED to store the empty-room recording along with that subject and session.

In either case, the label for the [`task-<label>`](../appendices/entities.md#task) entity in the empty-room recording SHOULD be set to `noise`.

in BIDS, a session is always "per participant" (that is, you would not have two participants listed in the same session directory)

Suggested change
One empty-room recording per each participant's session, stored within the session directory.

This was to clarify that in the other example (1) you can store under one session the noise recording to be used for multiple participants, but it's true it is redundant. How to store the emptyroom recordings is the thing I typically get the more questions about, as it is very MEG specific not applicable to other modalities, that's why I might have been over redundant in many places :)

One empty-room recording per each participant's session, stored within the session directory.

okay, let me try to push a commit and we can see whether you think that's an acceptable improvement.
